This is very strange. My up-to-date LMDE system was giving me trouble i.e. unexplainable desktop/app freezes multiple times a day, becoming worse over time. I decided to simply re-install it on a spare partition and copy all my old stuff over -- which is working just great since I have had no more freezes.
From my past experiences with sound problems on my LMDE machine, I knew I had to add the following entry to '/etc/pulse/default.pa' in order to prevent the non-sound-capable HDMI digital connection being used:
Code: Select all
set-card-profile 1 output:analog-surround-41+input:analog-stereo
This helped to get sound working again, including in Firefox -- but NOT in Chrome! This despite the fact that it is the same version of Chrome (37.0.2062.94) that I was already using. Using various diagnostic techniques (i.e. pavucontrol) I learned that the Chrome 'app' was NOT sending any sound to any of my sound devices. I compared back to my previous working LMDE, and noticed that it was an app named 'chromium' (not 'chrome') that was the working source source -- but in my new LMDE install there is no such activity. Here is a screenshot showing the working activity:
In this screenshot, 'ALSA' is what Firefox is using for sound playback (e.g. YouTube) and 'Chromium' is what Chrome is using for sound playback. This Chrome sound playback is missing in my new LMDE installation.
Help? Comments? I also installed Chromium, which works just fine (using 'Chromium' as the sound source, naturally I guess).
There is nothing more dangerous than a bored cat.
