On Ubuntu 12.04.3, I'm seeing [alsa-source] alsa-source.c: ALSA woke us up to read new data from the device, but there was actually nothing to read! [alsa-source] alsa-source.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers. [alsa-source] alsa-source.c: We were woken up with POLLIN set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. in the syslog. It also seems I have no access to the usual alsamixer volume controls on running alsamixer. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/329620 Title: ALSA woke us up to write new data to the device, but there was actually nothing to write.
