Hello,
does someone tried to install Trinity on Ubuntu Precise?
Today I upgraded my system from Oneiric to Precise due to new hardware that did not work
properly on Oneiric.
Everything works fine in Precise, except the sound. While I still have sound in gdm or
in unity DE I don't hear anything in Trinity.
Since the sound works already in gdm I think it should also work in Trinity if Trinity
would not touch it at startup. Unfortunately Trinity does. Shortly after the start the
sound gets somehow deactivated or invisible muted (in alsamixer everything looks fine,
volume is up not muted). However, I don't hear anything and I don't get any error
messages). What can I do?
The first thing I'd recommend is to launch Kmix and see if it agrees with alsamixer.
If it does, go into Control Cente -> Sound & Multimedia -> Sound System. Try to
disable it (untick "Enable the sound system", hit apply) and see if it works. If
not, then re-enable the Sound System and click the Hardware tab. Check the setting for
"Select the audio device". This is normally set to "Autodetect", but
it may be worth while to specify one specificly. Since you're using ALSA, that would
be the first one to try, followed by the others if you have any listed.
The "last resort" thing I'd recommend is to use either apt-get or Synaptic
to purge/completely remove ALSA, then reinstall it.
