Comment 1 David L. Parsley 2008-12-08 12:42:58 EST
My default PCM volume was very low, so that I had to crank my speakers and all volumes all the way for it to be audible.  When I fired up 'alsamixer -c 0', the PCM volume was at around -21dB.  I brought it all the way up to +12 to make it usable.  My card from lspci:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)
This is from a recent model Dell Optiplex 745.

In F10 PA doesn't init the audio volume unless it has some previously saved volume to restore. 

It's ALSA's job to come up with sane defaults. REassigning to alsa.

Could you copy the latest /lib/alsa/init/default file from this localiton http://git.alsa-project.org/?p=alsa-utils.git;a=blob_plain;f=alsactl/init/default and test if 'alsaunmute' script sets the default volumes correctly for your hw? Thank you.

Shows this message:
Unknown hardware: "ICH4" "Realtek ALC202 rev 0" "AC97a:414c4740" "" ""
Hardware is initialized using a guess method
but,yes, sets the correct PCM and Volume Value.

Bye and Tks by your fix.
