check your soundchannels see if they are muted
If the channels show an M at the top they are muted m key will unmute
If you havent got alsa installed go download the source and read the alsa howto www.alsa-project.org
I have the Intel 82801DB on board sound card (with AC'97 codec).
RH 8.0 linux 2.6
I built the alsa modules. The driver for the card is snd-intel8x0. I modprobe this module and also modprobe the snd_pcm_oss and snd_mixer_oss modules.
I ran 'alsaconf' to do the configuration of the card (i don't know what
all things it does. But after that I am able to play various formats
.wav, .mpeg etc.
However, I can not listen to my CD.
I use some instruction and do 'arecord | aplay' after doing the capture
on CD in the alsamixer. But what I get is a continuous grating sound.
Q : Is there any other way of listening to CD?
I capture the Mic through the alsamixer. The .wav files are created. But
either they are quiet or create the same grating sound when I use aplay.
The microphone/headphone are fine as I tested them on another PC (windows).. This brings me to suspect that the sound card may have recording problems. This is also suggested by someone in the stanford CCRMA mail exchanges.
Q.: How do I pinpoint the source of the problem? Is it the driver or the card that is the culprit?
I have a similuar problem... everything works accept midi all though I don't really care about midi cause I don't think this card really supports midi, in Windows XP when I pull up the mixer it says SW Synth ... so my midi driver is being emulated like timidity does on linux...
Or thats what I think anyways.. can anyone tell me if I'm right about the Intel8x0 chipset not supporting midi? (even though there are ALSA midi drivers)
I had the problem of not being able to hear my mic under suse 9.1 .... well if I made a hell of a noise I could just here it. in Windows XP and my bootable mandrake 10 cd it worked, so I went a searching on google with the key words: quiet microphone Linux I read somewhere about switching from mic 1 to mic 2 but didn't know where to do it and I ran # alsamixer and saw the mic 1 / mic 2 toggle and my troubles were over. I am writing this post so a google bot may find this some day and save somebody the trouble I had.
i'm not sure if this is your problem, but i had to get a cable to connect the sound card to the cdrom drive. something about simple programs like kscd or the cdplayer applet not support digital audio compression...or something. anyway, i think an easy way to test this is try playing a cd in XMMS or another bloated media player (these support it). if that works, then this is most likely your problem.
