I think I am suffering from the same problem on my Thinkpad T61p. Pulseaudio is complaining with the same messages, but I have some additional problems, maybe related: 1. S/PDIF (iec958) output has little (but annoying) clipping sound after each boot. solved by muting and unmuting in alsamixer. 2. Whenever a KDE program like Kopete tries to output sound at the same time as another program (Flash in Chromium for example) a notification pops up: "The audio device Intel HDA [...] has failed [...]" and I have no sound in Kopete. 3. Very irregularly I am unable to output any sound through S/PDIF output. I've checked *all* mixer settings with alsamixer and pulseaudio tools. Only switching to analogue gives me sound. After a reboot everything is working fine.
I am selecting the outputs from "Sound Preferences", in "Settings for the selected device", "Profile:". When testing the speakers in there I get no sound when issue (3.) occurs. All worked well in Maverick, didn't have any of the above issues. Using Ubuntu Natty in "Classic mode" (GNOME 2). Could it be that thinkpad-acpi stuff might be involved in the cause of all this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/773443 Title: [natty] pulseaudio stopped working on ThinkPad T61 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
