Public bug reported:
While the symptoms sound similar to case #237945 (and may share the same
root cause) the YMF-724F sound card (which appeared to be operating
correctly under 8.10) fails under 8.10.2.
Symptoms:
After performing the distribution upgrade, the volume control icon has a red
sign on it. Double clicking on the icon presents the message: No volume control
GStreamer plugins and/or devices found.
Running lshw -C sound gives the following:
