As a workaround, you can try to use OSSV4 instead of alsa. With TDE,
only OSSV4 tools (ossxmix is the mixer interface you can use in any
environment) have the control on OSSV4.
Link to configuration  :
And the sound is better than it is with ALSA.
I presume OSSV4 should be in repositories of precise directly as they
are in Mint. I recommend to install the DKMS packages if there are some,
that way you can configure your sound much further and better.
If you need some more explanation look at the OSS wiki page,

or ask at the OSS Linux forum if you are locked :

Of course, if I can first answer, just ask me, I'm not using precise,
but I guess that it's quite near from Mint 12 and oneiric ;)

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?

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.

> Thanks for your help.  Unfortunately, it did not help.  I also tried to remove or disable everything that could conflict with the sound system.  I removed pulseaudio and arts via aptitude, removed all autostart applications from /opt/trinity/share/autostart and ~/.trinity/Autostart, except kdesktop and panel, and deleted .trinity/share/config/ksmserverrc to start with a new and clean session.  However, the problem stays the same.  When KDE session manager (ksmserver) starts up my sound gets deactivated.
> As workaround I'm currently starting openbox instead of TDE.  In openbox I can run kdesktop, kicker, khotkeys without issues.  Sound works.  Only the start of ksmserver breaks the sound system, so I skip this one.
