In addition there +are few sound chipsets which are SB compatible in Linux such as ESS1688 or +Jazz16.

There are several +problems which you will encounter by using SB mode with cards that are not +truly SB compatible: + +- The SB emulation is at most SB Pro (DSP version 3.x) which means that +you get only 8 bit audio (there is always an another ("native") mode which +gives the 16 bit capability).

The SB compatible mode always requires special intialization which is +done by the DOS/Windows drivers. This kind of cards work in Linux after +you have warm booted it after DOS but they don't work after cold boot +(power on or reset). +- You get the famous "DMA timed out" messages. Usually all SB clones have +software selectable IRQ and DMA settings. If the (power on default) values +currently used by the card don't match configuration of the driver you will +get the above error message whenever you try to record or play. There are +few other reasons to the DMA timeout message but using the SB mode seems +to be the most common cause. + +2. Trying to use a PnP (Plug & Play) card just like an ordinary soundcard +------------------------------------------------------------------------- + +Plug & Play is a protocol defined by Intel and Microsoft. It let's operating +systems to easily identify and reconfigure I/O ports, IRQs and DMAs of ISA +cards. The problem with PnP cards is that the standard Linux doesn't currently +(versions 2.1.x and earlier) don't support PnP.

The voxware probe routines rely on the - fact that if the hardware is there, they can detect it. The problem - with AEDSP16 is that no hardware can be found by the probe routines - if the sound card is not well configured. Sometimes the kernel probe - routines can find an SBPRO even when the card is not configured (this - is the standard setup of the card), but the SBPRO emulation don't work - well if the card is not properly initialized. For this reason - - InitAEDSP16_...() - - routines are called before the voxware probe routines try to detect the - hardware. - - NOTE (READ THE NOTE TOO, IT CONTAIN USEFUL INFORMATIONS) - - The Audio Excel DSP 16 Sound Card emulates both SBPRO and MSS; - the voxware sound driver can be configured for SBPRO and MSS cards - at the same time, but the AEDSP16 can't be two cards!! - When we configure it, we have to choose the SBPRO or the MSS emulation - for AEDSP16. We also can install a *REAL* card of the other type - (see [1], not tested but I can't see any reason for it to fail). - - NOTE: If someone can test the combination AEDSP16+MSS or AEDSP16+SBPRO - please let me know if it works. - - The MPU-401 support can be compiled in together with one of the other - two operating modes. - - The board configuration calls, are in the probe_...() routines because - we have to configure the board before probing it for a particular - hardware. After card configuration, we can probe the hardware. - - NOTE: This is something like plug-and-play: we have only to plug - the AEDSP16 board in the socket, and then configure and compile - a kernel that uses the AEDSP16 software configuration capability. - No jumper setting is needed! - - For example, if you want AEDSP16 to be an SBPro, on irq 10, dma 3 - you have just to make config the voxware package, configuring - the SBPro sound card with that parameters, then when configure - asks if you have an AEDSP16, answer yes. That's it. - Compile the kernel and run it. - - NOTE: This means that you can choose irq and dma, but not the - I/O addresses. To change I/O addresses you have to set them - with jumpers. - - NOTE: InitAEDSP16_...() routines get as parameter the hw_config, - the hardware configuration of the - to be configured - board. - The InitAEDSP16() routine, configure the board following our - wishes, that are in the hw_config structure. - - You can change the irq/dma/mirq settings WITHOUT THE NEED to open - your computer and massage the jumpers (there are no irq/dma/mirq - jumpers to be configured anyway, only I/O port ones have to be - configured with jumpers) - - For some ununderstandable reason, the card default of irq 7, dma 1, - don't work for me. Seems to be an IRQ or DMA conflict. Under heavy - HDD work, the kernel start to erupt out a lot of messages like: - - 'Sound: DMA timed out - IRQ/DRQ config error?' - - For what I can say, I have NOT any conflict at irq 7 (under linux I'm - using the lp polling driver), and dma line 1 is unused as stated by - /proc/dma. I can suppose this is a bug of AEDSP16. I know my hardware so - I'm pretty sure I have not any conflict, but may be I'm wrong. Who knows! - Anyway a setting of irq 10, dma 3 works really fine. - - NOTE: if someone can use AEDSP16 with irq 7, dma 1, please let me know - the emulation mode, all the installed hardware and the hardware - configuration (irq and dma settings of all the hardware). - - This init module should work with SBPRO+MSS, when one of the two is - the AEDSP16 emulation and the other the real card. (see [1]) - For example: - - AEDSP16 (0x220) in SBPRO emu (0x220) + real MSS + other - AEDSP16 (0x220) in MSS emu + real SBPRO (0x240) + other - - MPU401 should work. (see [1]) - - [1] Not tested by me for lack of hardware. - - TODO, WISHES AND TECH - - May be there's lot of redundant delays, but for now I want to leave it - this way. - - Should be interesting eventually write down a new ioctl for the - AEDSP16, to let the suser() change the irq/dma/mirq on the fly. - The thing is not trivial. - In the real world, there's no need to have such an ioctl because - when we configure the kernel for compile, we can choose the config - parameters. If we change our mind, we can easily re-config the kernel - and re-compile. - Why let the suser() change the config parameters on the fly ? - If anyone have a reasonable answer to this question, I will write down - the code to do it. - - More integration with voxware, using voxware low level routines to - read-write DSP is not possible because you may want to have MSS - support and in that case we can not rely on the functions included - in sb_dsp.c to control 0x2yy I/O ports. I will continue to use my - own I/O functions. - - - About I/O ports allocation - - - The request_region should be done at device probe in every sound card - module. This module is not the best site for requesting regions. - When the request_region code will be added to the main modules such as - sb, adlib, gus, ad1848, etc, the requesting code in this module should - go away. - - I think the request regions should be done this way: - - if (check_region(...)) - return ERR; // I/O region already reserved - device_probe(...); - device_attach(...); - request_region(...); // reserve only when we are sure all is okay - - Request the 2x0h region in any case if we are using this card. - - NOTE: the "(SBPro)" string with which we are requesting the AEDSP16 region - (see code) does not mean necessarily that we are emulating SBPro. - It mean that the region is the SBPro I/O ports region. We use this - region to access the control registers of the card, and if emulating - SBPro, I/O SBPro registers too. If we are emulating MSS, the SBPro - registers are not used, in no way, to emulate an SBPro: they are - used only for configuration purposes. - - Someone pointed out that should be possible use both the SBPRO and MSS - modes because the sound card have all the two chipsets, supposing that - the card is really two cards. I have tried something to have the two - modes work together, but, for some reason unknown to me, without success. - - I think all the soft-config only cards have an init sequence similar to - this. If you have a card that is not an AEDSP16, you can try to start - with this module changing it (mainly in the CMD? I think) to fit your - needs. - - Started Fri Mar 17 16:13:18 MET 1995 - - v0.1 (ALPHA, was an user-level program called AudioExcelDSP16.c) - - Initial code. - v0.2 (ALPHA) - - Cleanups. - - Integrated with Linux voxware v 2.90-2 kernel sound driver. - - Sound Blaster Pro mode configuration. - - Microsoft Sound System mode configuration. - - MPU-401 mode configuration. - v0.3 (ALPHA) - - Cleanups. - - Rearranged the code to let InitAEDSP16 be more general. - - Erased the REALLY_SLOW_IO. We don't need it. Erased the linux/io.h - inclusion too. We rely on os.h - - Used the to get a variable - len string (we are not sure about the len of Copyright string). - This works with any SB and compatible. - - Added the code to request_region at device init (should go in - the main body of voxware). - v0.4 (BETA) - - Better configure.c patch for AEDSP16 configuration (better - logic of inclusion of AEDSP16 support) - - Modified the conditional compilation to better support more than - one sound card of the emulated type (read the NOTES above) - - Moved the sb init routine from the attach to the very first - probe in sb_card.c - - Rearrangements and cleanups - - Wiped out some unnecessary code and variables: this is kernel - code so it is better save some TEXT and DATA - - Fixed the request_region code. We must allocate the AEDSP16 (SBPro) - I/O ports in any case because they are used to access the DSP - configuration registers and we can not allow anyone to get them. - v0.5 - - cleanups on comments - - prep for diffs against v3.0-proto-950402 - v0.6 - - removed the request_region()s when compiling the MODULE sound.o - because we are not allowed (by the actual voxware structure) to - release_region() - - */ - - -#define VERSION "0.6" /* Version of Audio Excel DSP 16 driver */ - -#undef AEDSP16_DEBUG /* Define this to enable debug code */ -/* Actually no debug code is activated */ - -/* - * Hardware related defaults - */ -#define IRQ 7 /* 5 7(default) 9 10 11 */ -#define MIRQ 0 /* 5 7 9 10 0(default), 0 means disable */ -#define DMA 1 /* 0 1(default) 3 */ - -/* - * Commands of AEDSP16's DSP (SBPRO+special). - * For now they are CMDn, in the future they may change. - */ -#define CMD1 0xe3 /* Get DSP Copyright */ -#define CMD2 0xe1 /* Get DSP Version */ -#define CMD3 0x88 /* */ -#define CMD4 0x5c /* */ -#define CMD5 0x50 /* Set M&I&DRQ mask (the real config) */ -#define CMD6 0x8c /* Enable Microsoft Sound System mode */ - -/* - * Offsets of AEDSP16 DSP I/O ports.

If someone owns this + audio card and want to see the kernel support for it, please contact me. + + Audio Excel DSP 16 is an SB pro II, Microsoft Sound System and MPU-401 + compatible card. + It is software-only configurable (no jumpers to hard-set irq/dma/mpu-irq), + so before this module, the only way to configure the DSP under linux was + boot the MS-DOS loading the sound.sys device driver (this driver soft- + configure the sound board hardware by massaging someone of its registers), + and then ctrl-alt-del to boot linux with the DSP configured by the DOS + driver. + + This module works configuring your Audio Excel DSP 16's irq, dma and + mpu-401-irq. The OSS Lite routines rely on the fact that if the + hardware is there, they can detect it. The problem with AEDSP16 is + that no hardware can be found by the probe routines if the sound card + is not configured properly. Sometimes the kernel probe routines can find + an SBPRO even when the card is not configured (this is the standard setup + of the card), but the SBPRO emulation don't work well if the card is not + properly initialized. For this reason + + aedsp16_init_board() + + routine is called before the OSS Lite probe routines try to detect the + hardware. + + NOTE (READ THE NOTE TOO, IT CONTAIN USEFUL INFORMATIONS) + + NOTE: Now it works with SC-6000 and SC-6600 based audio cards. The new cards + have no jumper switch at all. No more WSS or MPU-401 I/O port switches. They + have to be configured by software. + + NOTE: The driver is merged with the new OSS Lite sound driver. It works + as a lowlevel driver. + + The Audio Excel DSP 16 Sound Card emulates both SBPRO and MSS; + the OSS Lite sound driver can be configured for SBPRO and MSS cards + at the same time, but the aedsp16 can't be two cards!! + When we configure it, we have to choose the SBPRO or the MSS emulation + for AEDSP16. We also can install a *REAL* card of the other type (see [1]). + + NOTE: If someone can test the combination AEDSP16+MSS or AEDSP16+SBPRO + please let me know if it works. + + The MPU-401 support can be compiled in together with one of the other + two operating modes. + + NOTE: This is something like plug-and-play: we have only to plug + the AEDSP16 board in the socket, and then configure and compile + a kernel that uses the AEDSP16 software configuration capability. + No jumper setting is needed! + + For example, if you want AEDSP16 to be an SBPro, on irq 10, dma 3 + you have just to make config the OSS Lite package, configuring + the AEDSP16 sound card, then activating the SBPro emulation mode + and at last configuring IRQ and DMA. + Compile the kernel and run it. + + NOTE: This means for SC-6000 cards that you can choose irq and dma, + but not the I/O addresses. To change I/O addresses you have to set + them with jumpers. For SC-6600 cards you have no jumpers so you have + to set up your full card configuration in the make config. + + You can change the irq/dma/mirq settings WITHOUT THE NEED to open + your computer and massage the jumpers (there are no irq/dma/mirq + jumpers to be configured anyway, only I/O BASE values have to be + configured with jumpers) + + For some ununderstandable reason, the card default of irq 7, dma 1, + don't work for me. Seems to be an IRQ or DMA conflict. Under heavy + HDD work, the kernel start to erupt out a lot of messages like: + + 'Sound: DMA timed out - IRQ/DRQ config error?' + + For what I can say, I have NOT any conflict at irq 7 (under linux I'm + using the lp polling driver), and dma line 1 is unused as stated by + /proc/dma. I can suppose this is a bug of AEDSP16. I know my hardware so + I'm pretty sure I have not any conflict, but may be I'm wrong. Who knows! + Anyway a setting of irq 10, dma 3 works really fine. + + NOTE: if someone can use AEDSP16 with irq 7, dma 1, please let me know + the emulation mode, all the installed hardware and the hardware + configuration (irq and dma settings of all the hardware). + + This init module should work with SBPRO+MSS, when one of the two is + the AEDSP16 emulation and the other the real card. (see [1]) + For example: + + AEDSP16 (0x220) in SBPRO emu (0x220) + real MSS + other + AEDSP16 (0x220) in MSS emu + real SBPRO (0x240) + other + + MPU401 should work.
