AD1981BThis is a Analog Devices AC'97 Audio controller Note: The documentation of the R40 incorrectly(?) states it has a AD1891A Features
|
Linux OSS driver
On systems where lspci shows an Intel AC'97 Audio Controller, this chip is supported by the i810_audio kernel module.
Linux ALSA driver
On systems where lspci shows an Intel AC'97 Audio Controller, this chip is supported by the snd-intel8x0 kernel module.
On systems where lspci shows an ATI AC'97 Audio Controller (R40e and R51e), this chip is supported by the snd-atiixp kernel module.
Note
On some models (T40, T43p, ...) audio is muted if either Headphone or Line Jack are unmuted. See also ALSA Wiki FAQ [1]
If You have problems with mixing, You may need to try this:
{
$ cat ~/.asoundrc
pcm.ossmix {
type dmix
ipc_key 1024
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 8192 # buffer size < 6653, but pow(x, 2)
rate 48000 # we want to play CDs only
}
bindings {
0 0
1 1
}
}
- Everything shall be dmixed, so redefine "default":
pcm.!default {
type plug
slave.pcm "ossmix"
}
}
# OSS via aoss should d(mix)stroyed:
pcm.dsp0 {
type plug
slave.pcm "ossmix"
}
ctl.mixer0 {
type hw
card 0
}
FreeBSD OSS driver
snd_ich will work happily for this audio chip.
