Hi.
I've got a Lenovo Thinkpad T400 with snd_hda_intel:
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) Subsystem: Lenovo Device 20f2
I think this is the same chip which recently quirks entries to work around docking issues on the Thinkpad x200.
The codec is identified as a conexant CX20561 (Hermosa).
Running Ubuntu 8.10 with 2.6.27, the Volume is extremely low. Quality seems okay, but setting Master and PCM outputs to 100% is barely audible. There's a bunch of similar reports on the Internet. I could not find any workaround but Window users usually report the volume should be fine.
I tried 2.6.28 but to no avail. Will verify against latest git.
Could someone help me fix this? I don't actually know much about the hardware in question, but would also willing to poke a little around in patch_conexant.c, if that could help identifying the issue. Provided someone someone around here has advice on what to try out.
Cheers, Daniell
