Hello Everyone,
I know I will find a fix for this eventually, but I have to admit that it is getting tiresome "fixing" something that gets broken with a large update. The most recent 41 updates (today) included a number of puse audio updates and of course now sound is broken. There is at least one other thread currently that complains about these same updates (which included nm) breaking their wireless. This is at least the fourth time since installing 8.10 that a large set of updates has damaged an otherwise working system, requiring sometimes considerable time to fix. This seems to be a fairly recent development because in all the years I have been using Ubuntu, I don't recall this being an issue.
Now, I am a reasonably experienced user (not an expert), but for all the new people just trying out the newest Ubuntu, things like this could be a deal breaker.
I apoligize and I know I will get some biting responses, but I right now I am just a little frustrated that yet again I have to fix something that wasn't broken before an update. I guess I just needed to vent.
By the way, just in case anyone else has the issue, all the usual commands to test sound work as usual, just no sound. When clicking the test button, I get:
"audiotestsrc wave=sine freq=512 !
Failed to connect to stream"
Not the whole error, but enough to investigate. And the Sound Preferences GUI freezes and has to be forced to close.
I will dig around and find an answer, but if some kind soul knows the answer to this and can save me a few hours, I would be very appreciative.
