Created attachment 669789 [details] audio related syslog messages Description of problem: When I do some (e. g. 2) hibernate-thaw-cycles I cannot use HDMI audio anymore. It doesnt happen each time, but i have to reboot if i want to fix it... I use os: Fedora Core 17 (fully updated) sound system: pulseaudio cpu: AMD A10-5800K mainboard: GigaByte GA-F2A75M-D3H Version-Release number of selected component (if applicable): Linux vaako.intern.wgboome.org 3.6.10-2.fc17.x86_64 #1 SMP Tue Dec 11 18:07:34 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux How reproducible: sometimes 3 thaw-s r successful... Steps to Reproduce: 1. start mplayer and pause 2. hibernate-thaw 3. continue mplayer Actual results: Sometimes there is no sound with the following symptoms: Pulseaudio's volume meter either shows zero volume or the volume bar doesnt flicker as rapid as it should and video playback is slow and jumpy. When I switch the mplayer process to the analog audio sink, audio+video work fine again. Restarting pulseaudio+mplayer doesnt help. Reloading the kernel module (fglrx) doesnt help. Rmmod-ing the snd_hda_intel module crashes the box. Expected results: audio should work after thaw like it did before hibernate... Additional info: i added audio related syslog lines i filed a bug report here: http://ati.cchtml.com/show_bug.cgi?id=681
i found a workaround: 1. i do this before hibernate: > ( echo set-card-profile alsa_card.pci-0000_00_01.1 off ; \ echo set-card-profile alsa_card.pci-0000_00_14.2 off ) | pacmd 2. and set the proper profiles after thaw 3. when the HDMI profile fails, then i let it hibernate-thaw again (with profiles set to 'off'), but in fake mode (in order to avoid a power cycle): # echo reboot > /sys/power/disk does it help to debug that problem? why is it, that the HDMI audio sometimes thaws properly and sometimes it doesnt?
it seems like it is fixed now (since a week or so)... :-)
