Driver for Sound Blaster 16 and compatible sound cards.
|You must be root to start this driver.|
Direct invocation (also causes a new io-audio process to start):
io-audio -dsb ioport=port,irq=req,dma=ch,dma1=ch &
Mounting (requires that io-audio is already running):
mount -Tio-audio -oioport=port,irq=req,dma=ch,dma1=ch \ /lib/dll/deva-ctrl-sb.so &
x86 only (requires ISA bus)
The deva-ctrl-sb.so shared object is a DLL for the io-audio manager. It uses the API described in the Audio Developer's Guide.
While deva-ctrl-sb.so is running, you can use applications with sound, and those that control the sound-system (e.g. mixer).
|Graphics drivers run at a higher priority than applications, but they shouldn't run at a higher priority than the audio, or else breaks in the audio occur. You can use the on command to adjust the priorities of the audio and graphics drivers.|
When an error occurs, deva-ctrl-sb.so sends a description of the error to the system logger (see slogger).
Some sound cards listed as being Sound Blaster compatible default to another mode (e.g. some ESS 18xx series (not ESS 1869), OPTi 931, Yamaha OPL3-SA). These cards will not work with this driver.
