I have on my motherboard intel hda analog audio and my graphics card (an ATI) had an HDMI out; by default I like the audio to come out of the analog output that is the only one connected. Sometimes logging into KDE I find that it's decided to switch to the HDMI as the default; today I caught it and did an lsof /dev/snd/* and found: knotify4 2276 dg mem CHR 116,3 6691 /dev/snd/pcmC0D0p knotify4 2276 dg 20r CHR 116,33 0t0 9995 /dev/snd/timer knotify4 2276 dg 21u CHR 116,3 0t0 6691 /dev/snd/pcmC0D0p pulseaudi 2893 dg 24u CHR 116,9 0t0 6698 /dev/snd/controlC1 pulseaudi 2893 dg 31u CHR 116,6 0t0 6694 /dev/snd/controlC0 pulseaudi 2893 dg 38u CHR 116,6 0t0 6694 /dev/snd/controlC0 So knotify4 has hogged the analog output, and hence pa can't get in. So I kill knotify4, and do a pactl exit to restart pa - but pa then still lists the HDMI as the default output in paman. (I've now found I can switch it back with pacmd set-default-sink) Dave Reproducible: Sometimes Steps to Reproduce: It's a race, so only happens sometimes. 1) Login 2) Try to play some music 3) Find it doesn't play 4) lsof /dev/snd/* to see who has what devices Actual Results: No music coming out of my analog output. lsof shows knotify4 hogging the analog device Expected Results: Sweet music on my analog output, pa has opened all the devices.

It's been working pretty well for me! See the canberra branch here: http://colin.guthr.ie/git/kdebase-runtime/ It's pretty old now but should apply cleanly still if you want to try it out. The whole default device thing shouldn't really matter under KDE (provided you run start-pulseaudio-kde after restarting PA to reload the module-device-manager module) this is run automatically at startup and in future releases will be baked into PA itself so will be deprecated.... that's a good few months away tho'.

After wasting time reading about how to find various types of audio bugs, and then relearning that HDMI is for output (I've never used it), I finally realized that the problem was simply that KMix had chosen my HDMI as the "master channel" and I needed to change it to my built-in audio. If this bug is related to my problem, it will be great if it will be fixed soon, because I can imagine unsavvy users giving up on KDE when they can't discover how to fix the problem before their patience expires.

This is Gentoo. Two identical systems, on one PA wins and all is peachy. On the other however knotify4 wins and PA misses the default audio device. All you can do at that moment is: * kill knotify4 * kill PA * kill knotify4 AGAIN * start PA * restart kmix Reply at: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/875660/comments/16 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/875660 Title: PA and knotify startup race leads to wrong device selection Status in Phonon: New Status in “kde-runtime” package in Ubuntu: Confirmed Status in “pulseaudio” package in Ubuntu: Confirmed Bug description: This appears to be a regression in Oneiric.

I'm also going to subscribe this bug to kde-runtime; I'm not sure who is supposed to manage the race between pa startup and anything else, and I'm not sure if it's a kubuntu special or KDE in general.
