I ran into a new problem while working on my BLFS system. I am using
version 6.2 of the book, but in this case just as a guide. I have
compiled ALSA-lib, ALSA-utils, ALSA-plugins and in my case,
ALSA-driver. I have deviated from the book in that I am using ALSA
version 1.0.15, mainly because I could not get version 1.0.13 to work.
My problem is that I can get everything working fine as "root", but get
the following error when I try "speaker-test" as a normal user.
/speaker-test 1.0.15
Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels

/I have also installed mpg123 per the book instructions. If I play an
mp3 file as "root" it plays just fine. If I try to play the same file
as a normal user I get the following.

/I have tried searching google, and have read all of the README's in the
ALSA tarballs and cannot seem to find an answer. I am hoping that one
of you can point me in the right direction. If it matters, I am using
kernel 2.6.23.12 with my sound card compiled as a module. The card, as
identified with "lspci" is as follows.
/00:06.1 Audio device: nVidia Corporation MCP55 High Definition Audio
(rev a2)/
The output of "lsmod" is as follows.
