Can anyone direct me to a FAQ about Debian Audio and Sound drivers??

I had an issue with sound, so i basically installed everything under the sun.

Do not know what i did, but got it to work. Unfortunately I think some
drivers are stepping on other drivers.

I think i install pulseaudio, alsa, and the kitchen sink.

How can i know what is really work and how can i check to disable the rest ?????

when i run lspci |grep audio, I get the following:

rider:/# lspci |grep audio
00:04.0 Multimedia audio controller: nVidia Corporation CK804 AC'97
Audio Controller (rev a2)
rider:/home/mjh#

when i run lsmod , i get the following :

rider:/# lsmod |grep audio
snd_usb_audio 88736 0
snd_usb_lib 21888 1 snd_usb_audio
snd_hwdep 15240 1 snd_usb_audio
snd_pcm 89096 6
snd_usb_audio,snd_intel8x0,snd_ac97_codec,snd_pcm_ oss
snd 65256 16
snd_usb_audio,snd_seq_oss,snd_seq,snd_rawmidi,snd_ seq_device,snd_hwdep,snd_intel8x0,snd_ac97_codec,s nd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer


My current issue is that the audio for the is very low, no matter how
high i raise the volume.

thanks
mjh

Well, the drivers are unlikely to step on each other like that, however
the user-lever sound stuff might. Right now it sounds like there may
be places to adjust the sound level that you haven't checked yet.

likely volume controls from most low level to highest level:

alsa volume - set with alsamixer, alsamixergui or gnome-alsamixer

pulse-audio volume - set with pavucontrol/pulse-audio volume

App volume control - in media player, etc.

Have you checked all of these, and are you running Gnome,
KDE3, KDE4, or other?


Cheers,

Although these documents are ancient, they may provide some useful
information. Install the doc-linux-text package and read these:


/usr/share/doc/HOWTO/en-txt/Alsa-sound.gz
/usr/share/doc/HOWTO/en-txt/Sound-HOWTO.gz
/usr/share/doc/HOWTO/en-txt/Sound-Playing-HOWTO.gz

The Linux kernel documentation also has some files that describe the
sound system; I hope they are not too obtuse for you; they are for me :-


If you install the kernel documentation, you'll find the sound files for
ALSA in ./Documentation/sound/alsa. Don't bother with
./Documentation/sound/oss unless someone tells you to look in there. OSS
is a very ancient Linux sound system that ALSA has largely replaced.
