Intel HDA Audio - No sound: With a Twist!
My laptop, with the Intel HDA ICH 7 audio controller is not outputting any sound, usually. I am running the 126.96.36.199 kernel with sound support compiled as modules. The card seems to be working fine (the relevant modules are loaded, it appears in alsaconf and alsamixer, but no sound is output, usually. As far as I can tell (I am running madplay with a known good mp3 file to test), the sound card will only output sound for one command after bootup. If I, say, ctrl-c out of the program and start it again, I get no sound. I can understand sound not working, but this inconsistent pedrformance is really irritating me.
Where would I find relevant error messages?
Should I download the newest ALSA drivers?
Is there some other arcane magic that might be invoked to get this sound card running properly?
I will gladly provide any more information that might be useful.
