[alsa-devel] snd-hda-intel AD1981 - Sound volume low level
Hi, I just want to ask you if you have heard about the problem with low sound volume level even though you set the alsamixer on the (almost) maximum volume level. The sound card: snd-hda-intel / AD1981 / ICH7 )
It's a big problem for me especially when I watch a movie with ac3 (DVD quality) decoded sound. The volume level is extrimly low in such situation (I mean the level you hear the sound). I have to connect my loudspeakers to a ampilifier and set it in very high level.
I don't have such problem when I work with Windows XP. They are loud enough.
That's alsa-info.sh result: http://pastebin.ca/908831
It is said that there are some preferences in the totem package (hidden in alsamixer) that can fix it and make alsa to remember higher sound level.
I've noticed that problem with all kernels I tested (I've checked about 15-20 kernels from that range 2.6.13.x - 2.6.24.x) (I usually use vanillia kernel (from www.kernel.org) /with build alsa/). But I've tested the newest alsa-drivers: 1.0.16 with 2.6.24.2 kernel also and the result was the same.
Could you chack that problem, please?

First of all, use HG version if you want to debug the problem. 1.0.16 is already too old and sticking with this version makes a lot of problems (e.g. hitting the bugs that have been already fixed).
Looking at your alsa-info output, the Master volume isn't set to the maximum. But, I guess it doesn't matter (not loud enough) even with the max Master volume, right? And, the question is about the headphone output or the speaker, or both?
I see no obvious problem in the codec setup. One thing we can try is to change the connection of output pins directly from the DAC.
Use hda-verb program to do this kind of thing without changing the driver code: ftp://ftp.suse.com/pub/people/tiwai/misc/hda-verb-0.2.tar.bz2
After compiling it, run as root like
# ./hda-verb /dev/snd/hwC0D0 0x06 SET_CONN 0
and see /proc/asound/card0/codec#0 whether the connection of the widget 0x05 is changed to the first one (pointing 0x03).
