Okay, home again and ready to test the latest stuff on the Lenovo x100e. This was with today's snapshot of sound-2.6, which includes commits 447ee6a7 and d507cd66, and with Andiry's disable-64-bit DMA patch [1] on top of that.
With PulseAudio installed, it happens almost every time. I have also reproduced the issue without PulseAudio, although only once. What I did then was the following: 1) Write some garbage in the beginning of /etc/pulse/default.pa to prevent PulseAudio to start up. 2) Started: arecord -Dplughw:0 -f cd test.wav 3) With that stream running, opened a second terminal window and started: speaker-test -Dplughw:0 -c 2 -t sine Now both applications crashed and the interrupts on the hda_intel line went up with ~400000 interrupts. Error message from arecord: arecord: pcm_read:1692: read error: Input/output error Error message from speaker-test: Write error: -5,Input/output error xrun_recovery failed: -5,Input/output error Transfer failed: Operation not permitted There is also a dmesg message: "hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x010f0600", but I'm 100% sure it came from the exact point when these applications crashed. I tried to reproduce the same thing, but it only happened once. -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic [1] https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/741825/+attachment/2123974/+files/snd_test.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/741825 Title: ATI controllers [1002:4383] and [1002:4383] (rev 40): Intermittent record and jack sense failure -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
