Over the network, i.e. with a remote PULSE_SERVER set, I get a lot of rewinds when a stream is playing. The frequency is high, in the 2-4 Hz range. Acoustically it sounds like about three fadeouts per second, as if someone would move a fader up and down all the time. I have Kernel 2.6.27-3 and PA 0.9.12. The log looks like this:

I’m unsure if the frequency somehow correlates with this: D: alsa-util.c: Maximum hw buffer size is 371 ms [...] I: module-alsa-sink.c: Using 1 fragments of size 65536 bytes, buffer time is 371.52ms -- [PPA 0.9.12 regression], Wakeup from ALSA!, Underruns > rewinds https://bugs.launchpad.net/bugs/268891 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
