Comment 1 Frank DiPrete 2005-10-16 13:43:30 UTC

OK - found a work around.

By chance I tried un-muting the HEADPHONE control. With headphone jack sense
muted and headphone un-muted there is now sound. The headphone volume control
also controls the level of sound output.

There are 3 audio jacks on the system. line in, mic in and line out. For some
reason in this version of Fedora/Alsa the headphone volume control controls the
line out.

Found by luck.
