Hi debian folks,
I installed Debian last week (for the first time), and things
generally went very nicely.
One thing which isn't yet working though is sound. I'm currently
using the kernel from debian-backports
(linux-image-3.2.0-0.bpo.2-amd64) in order to get my ethernet
working, but the same thing happenned with the stock 2.6 kernel too
(linux-image-2.6.32-5-amd64)
Any suggestions at all of things to try would be most appreciated.
Below is hopefully relevant output from interesting commands.
Ok.. I know these may sound really naive... but with the integrated
audio thingies sometimes audio is really troublesome to set up even if
everything is working correctly, so:
- Are you 100% sure you have plugged your headphones/speakers in the
right output. This may seem funny but here e.g. I have front and rear
headphone jack and these are selectable from the alsamixer. I've seen
situations in which only one worked so you should try the combinations.
- On the same line try playing with levels and switches in (alsa)mixer
(or some other gui version) .. I have seen that sometimes when I
upgrade, for some unpredictable reason the PCM volume is turned down to
0 (PCM is basically all the audio you'll get from applications).
You would be surprised to know how many times I wasted time debugging
audio problems at the driver level and the issue was actually in the
(alsa) mixer, cables, plugs etc.
Good luck!
Lorenzo.
