Via 686/8233/8235 Audio Driver for Linux | ||

Two /proc pseudo-files provide diagnostic information. This is generally not useful to most users. Power users can disable CONFIG_SOUND_VIA82CXXX_PROCFS, and remove the /proc support code. Once version 2.0.0 is released, the /proc support code will be disabled by default. Available /proc pseudo-files:
/proc/driver/via/0/info /proc/driver/via/0/ac97 |
This driver by default supports all PCI audio devices which report a vendor id of 0x1106, and a device id of 0x3058. Subsystem vendor and device ids are not examined. The 8233 support covers all devices with a device id of 0x3059 and vendor id of 0x1106. Again subsystem ids are ignored as they usually hold the AC97 codec vendor information.
GNU indent formatting options:
-kr -i8 -ts8 -br -ce -bap -sob -l80 -pcs -cs -ss -bs -di1 -nbc -lp -psl |
Via has graciously donated e-mail support and source code to help further the development of this driver. Their assistance has been invaluable in the design and coding of the next major version of this driver.
The Via audio chip apparently provides a second PCM scatter-gather DMA channel just for FM data, but does not have a full hardware MIDI processor. I haven't put much thought towards a solution here, but it might involve using SoftOSS midi wave table, or simply disabling MIDI support altogether and using the FM PCM channel as a second (input? output?)
