Hi list! |
| 2 |
|
| 3 |
I've recently bought a Gigabyte GA-880GMA-UD2H board (AM3, integrated |
| 4 |
Radeon HD 4200). The problem is, sometimes sound works out-of-the-box. |
| 5 |
Then I reboot and there is no sound at all. There is no error - just no |
| 6 |
output. The SPDIF port (which I really need) does not emit any light, |
| 7 |
then. Sometimes after a cold reboot, it works again. |
| 8 |
|
| 9 |
I've found several threads pointing to problems with kernel 2.6.32 |
| 10 |
(solved in 2.6.33, I'm on 2.6.36). Some others made me wonder if alsa is |
| 11 |
confused by the HDMI output of the graphics card. I blacklisted |
| 12 |
snd_hda_codec_atihdmi and switched driver from fglrx to radeon but it |
| 13 |
did not change anything. I don't have the means to check whether there |
| 14 |
is any output over HDMI. |
| 15 |
|
| 16 |
I know that at least Volker has a similar board. Maybe others as well. |
| 17 |
Does someone have a clue what's going on? |
| 18 |
|
| 19 |
I'll append some info. |
