In this file I will try to build a database of cards supported by this driver. I also include the command to use for manual configuration of the card in case your BIOS is not PnP-aware. Of course it is your responsibility to pick up free prot ranges and irq and drq channels. For PnP cards, I also include the vendor_id and serial numbers of cards I have encountered. Underscores in the PnP id mean that there is a large variety of values in those positions. Finally, where available, I have put the URL where you can find the data sheets of the chip. CS4236: PnP id 0x36__630e CS4237: PnP id 0x37__630e http://www.crystal.com/ 4237full.pdf pnp 1 0 os enable port0 0x534 port2 0x220 irq0 5 drq0 1 drq1 3 work like a charm. All modes, including full duplex, supported in MSS mode. NOTE: cards based on the 4237, and possibly the 4236 as well, connect the CD to AUX2. When used in MODE1/2 (as this driver does) there is no route in the input mixer from AUX2 to the ADC. So, to record directly from the CD, the only way is to set the input to SOUND_MASK_IMIX. CS4232: PnP id 0x3242630e pnp 1 0 os enable port0 0x534 port2 0x220 irq0 5 drq0 1 drq1 3 This chip is reported as broken in the OSS documentation. As a matter of fact, on my Intel Zappa motherboard, I have problems in make it use the secondary DMA channel. I have it working in half duplex (both capture and playback) in SB3.2 emulation, and working in playback mode in MSS emulation. Also have reports from some user that it works ok. OPTi931: PnP id 0x3109143e http://www.opti.com/ opti931_21.pdf pnp 1 1 os enable port0 0x534 port2 0x220 port3 0xe0d irq0 10 drq0 1 drq1 6 The data sheets of this chip are very cryptic and do not match what the cards I have seem to do. I have it working in WSS emulation, in full duplex and all modes. In SB emulation mode the driver does not work yet (maybe I do not initialize it the right way). It is not a major concern anyways. I am strongly convinced of a couple of bugs in the chip. I have sent email to OPTI but got no reply so far. The bugs are: - you cannot set both playback and capture format to use a companded mode (ULAW, ALAW). If you do, the card will screw up on the capture section. The driver has a partial fix in software: when using ULAW, it programs ULAW on the playback section, U8 on the capture, and does a conversion in software (much like the SBPro). Of course you lose 4-5 bits of dynamic range in the process. - in full duplex (and single DMA mode), the card occasionally misses interrupts, or generates spurious ones. Spurious ints are not problematic since they can be ignored, but missed ones are as you can imagine... This is fixed by auto-dma mode. SB16 PnP: PnP id 0x__008c0e http://www.creative.com sbhwpg.pdf or SBHWPG.EXE pnp 1 0 os enable port0 0x220 irq0 5 drq0 1 drq1 5 There are many such cards (plain SB16 PnP, AWE32, AWE64, Vibra16, etc.) all differing in the PnP id. They have different synthesis devices, which we do not support, so we are not affected by these differences. Don't worry if the driver identifies the card as a different SB16 than the one you have. Full duplex support of this card is tricky since one channel can work in 16-bit and the other in 8-bit mode. You will need to use the new set of ioctl to use separate data formats on the two channels (the vat driver does this). Of course, quality in 8-bit is much lower than in 16-bit. Full duplex operation is unsupported by Creative. It seems to work, although on my Vibra16 the command to stop DMA transfer seems to erroneously affect both channels instead of the one they are issued for. The driver has a workaround, but I cannot guarantee that it works for everybody. I have had several positive reports. Some docs on how to use this card with the voxware driver are at http://multiverse.com/~rhh/awedrv NOTE: 980122 I have had a couple of reports from people using the Vibra16X (and clones, e.g. based on the Avance Logic chipsets) which appears to use two 8-bit DMA channels. It might be possible that new SB16 are able to do true full duplex! The driver _does not_ support these boards although the fix should be relatively easy. ASound: Avance Logic makes SB clones, and apparently documentation is available at http://www.realtek.com.tw/cp/cp.html these card should be recognised as SB16 clones. Yamaha SA2/SA3 http://www.yamaha.com ? YM711.pdf (this is a huge file containing a few pages scanned and converted to pdf. Not very useful or detailed.) pnp 1 0 os enable port0 0x220 port1 0x530 irq0 5 drq0 1 drq1 5 this card emulates a WSS or SB. Have reports that it works, although it has incomplete mixer support (Yamaha defines an additional set of registers to control some mixer functions, such as the master output volume). Currently we set the master volume to 100%. Driver reported to work also on Toshiba DynaBook Portege 300CT with OPL3SA-3(non-PNP) Ensoniq Soundscape VIVO pnp 1 0 os enable port0 0x220 port1 0x530 irq0 5 drq0 1 drq1 5 this card emulates a WSS or SB. Have reports that it works. GusPnP: PnP id 0x0100561e pnp 1 0 os enable port0 0x220 port1 0x320 port2 0x32c irq0 5 drq0 7 drq1 5 It works in U8 and S16 mode, ulaw support still not working. NOT WORKING YET: OPTI925: PnP id 0x2509143e there is code to recognize it as a SB clone. I have reports that it probes ok, but not sure if it works. OPTI924: PnP I have this card but it is still unsupported. OPTI930: should work as an MSS clone, but support for it is not implemented yet. ESS1868 ESS688 http://www.esstech.com pnp 1 1 os enable irq0 7 drq0 1 port0 0x220 There used to be documentation for the 1868 on the ESS site (files ds1868b1.pdf and ds1868b2.pdf) but I am unable to find it now (980122). I have asked ESS but no reply so far. partly supported in SB emulation. (the ESS688 is used on many notebooks. It is probably able to do 8 and 16-bit, half duplex). PCI cards: some vendors have PCI cards. This code _cannot_ work on these cards as it is now, since they cannot obviously use the ISA DMA controller. As there are no data sheets available for these PCI cards, none of them is supported at the moment, although support should be easy as soon as I can put my hands on the data sheets and cards.
