Nikos, the source of the script is available for inspection and
modification at http://www.alsa-project.org/alsa-info.sh

The script simply collects system information such as one's Linux
distribution, versions of necessary debugging information (alsa-lib,
alsa-utils, alsa-kernel/linux), mixer volume settings, ownership and
modes of /dev/snd/*, and contents of AC'97/HDA codec spew.

If you feel hesitant in any fashion regarding providing the above
debugging information to help developers resolve driver bugs, please
don't download, and don't run the script. Your bug reports, of course,
will receive little attention due to the lack of necessary debugging
information.

With respect to the revision history of the script itself, several
insecure temporary file uses have been corrected. The above URL always
redirects to the most current (git HEAD) version of the script. Of
course, run the script as an unprivileged user.

Bug description:
Reporting this bug for another user...

In MacBook and MacBookPro 5,1 (aluminium, late 2008) the soundcard works out of the box only with headphones, and to turn speakers on it is necessary to manually set the 6 channels. In that case, sound is heard both on headphones and right and center speaker; the left speaker doesn't work yet.

This bug is confirmed by several users, see the additional information attached.
