Re: F10 Strange Audio Errors

I'm seeing strange audio issues(skipping and buffering) when playing
audio from Amarok(1.4), Audacity and from the video game Quake Wars.

I have an on-board sound card:
00:04.0 Multimedia audio controller: nVidia Corporation CK804 AC'97
Audio Controller (rev a2)

And a USB Turntable:
Bus 002 Device 005: ID 08bb:2900 Texas Instruments Japan PCM2900 Audio

Periodically, while Amarok(1.4) is playing back I see:
Dec 25 16:48:45 localhost pulseaudio[15582]: module-alsa-sink.c: ALSA
woke us up to write new data to the device, but there was actually
nothing to write! Most likely t
his is an ALSA driver bug. Please report this issue to the PulseAudio

When Audacity is recording from the USB turntable I see:
ALSA sound/usb/usbaudio.c:351: frame 0 active: -70

And when Quake Wars is running, I see the following in the console
snd_pcm_readi failed: Input/output error
snd_pcm_readi failed: Input/output error
snd_pcm_readi failed: Input/output error

Any ideas as to what is going on here?


I'm having the same in F10. My log is full of those messages, I would
even say there is nothing in it except these errors, because it keeps
popping up every 2 minutes even if there is no program producing sound.
And when something is actually playing sound it is skipping like crazy and drives me nuts. I'd like to keep using pulseaudio, because some of my software is having errors without it, but this is unbearable. And the ticket has been there for more than a month http://www.pulseaudio.org/ticket/420 but I've seen no response from developers so far, whether it is even pulseaudio bug (do I remember something about skipping-free sound in release notes?) or alsa bug.

I'm running F9 x86_64 and F10 i386 on x86_64 hardware, should this matter.
