Very low audio level in F11
I recently upgraded from F10 to F11 (clean install). Now I have minimal audio volume. With the volume controls in Gnome all the way up and the speaker volume at max it's barely loud enough for background music. My initial expectation was that I had either not installed something or uninstalled something I shouldn't have, so I went back and reinstalled PulseAudiio using another machine running F11 that everything works on to make sure I had all the needed files. No change.
I have found several references to sound problems in F11, but none reference this problem. Sound "card" is built-in VIA VT1708/A according to the sound applet. MB is (I think) MSI K9VGM-V with Athlon64 X2 4400 cpu.
Everything worked fine in F10, and (unfortunately) this is a dula boot system, with everything working fine in Win, so it's not a hardware problem.
I appreciate any suggestions as to where to look for the problem.
