Comment 9 for bug 107232

Same problem here running 8.10 with updates to date on HDA Intel ALC888 analog / digital.

It's consistent across all apps - Firefox, Songbird, VLC, Rhythmbox, Totem, etc. I'm using headphones.

Every volume control is set to 100% (Alsa, PulseAudio, Alsamixergui) and also tried pushing playback stream over 100% in PulseAudio Manager, but this caused distortion.

I've tried every device available in Sound Preferences.

I found the following in /var/log/messages:

HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
alsa-util.c: Device hw:1 doesn't support 44100 Hz, changed to 16000 Hz.
alsa-util.c: Device hw:1 doesn't support 2 channels, changed to 1.

I haven't been able to find instructions on how to change that 'low' level - or even if it is relevant.
