| Hello,
| how did you solve it in the end? Recently, I have got my new
| machine with ASUS P4P800-VM with AD1980 and I came into exactly
| same problem with no sound. Oleg's patch was very good starting
| point how to get working sound and where to start ;o)
Yes, I'll commit it shortly.
| I have another machine with different problem: Output is good, however
| main volume is not adjusted by Master Volume (0x02) register, but by
| Headphone Volume (0x04) register (Monitor Volume in Aumix).
There's a patch below that should help with this case - let
me know how you go as I have no similar h/w.
| It is just though, but maybe my and Oleg's machine is case 3 in
| 5.2.1 AUX_OUT Options and the another machine would be case 1 or 2,
| so that it is needed to implement checking procedure at the end of
| 5.2.1 AUX_OUT Options. However, I have to access the another
| machine and check its chipset and registers first. If there is
| anybody with AD1980 chip too, it would be interesting to see content
| of 0x00, 0x04, 0x28, and 0x38 registers and experiences with current
| pcm driver.
The existing code does something already (ac97_fix_auxout in ac97.c),
but the available options are limited by the OSS mixer interface.
Kind Regards
