This has been happening to me since upgrading to 9.04 from 8.10.
I reproduce it the following way:
1. start pulseaudio (after making sure it's not running)
2. mplayer something
3. pause for about 30 seconds (does NOT seem to reproduce if the pause is
shorter)
4. resume playing, it breaks as described below
5. (only sometimes) mplayer something again, fails the same way
6. mplayer something again, it works but the line counting how far it goes
gets frozen, and if it's a video, there is no video output
7. goto step 2 (you can reproduce it again)
At any moment you can kill pulseaudio and it go back to step 1.
When it breaks in step 4, I hear only static and it plays too fast, as if it was
skipping samples, and then pulseaudio uses 100% CPU for about 10 seconds,
then goes back to the usual ~0%. There is no output when this happens.
When I start pulseaudio, I see the following:
$ pulseaudio
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
I: caps.c: Dropping root privileges.
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
W: alsa-util.c: Device hw:1 doesn't support 44100 Hz, changed to 48000 Hz.
W: alsa-util.c: Cannot find fallback mixer control "Mic" or mixer control is no
combination of switch/volume.
There is no output beyond that in all of my tests, and there is nothing related
in the kernel logs.
My sound card is an on-board Intel, lspci says:
Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)
My motherboard is an Intel DG36EC. I'm using a 2.6.29.1 (unpatched)
kernel.
I'm up to date with packages, the currently installed pulseaudio version is
0.9.14-0ubuntu20.
If you need anything else, please let me know.
Thanks a lot,
Alberto
