I tried both FN-F4 and Suspend through gnome menu. What Ubuntu version did succeed? Do you still have a T2x laptop to test that? I am using Ubuntu since 8.04 and never brought that to work.
I also tried the sudo alsa force-reload as mentioned in other comments to similar bugs. This brings sound back, however it kills every application that uses sound. So this is not an option. I tried to add all modules "snd-seq-dummy snd-seq-oss snd-seq-midi snd-seq-midi-event snd-seq snd-pcm-oss snd-mixer-oss snd-cs46xx snd-ac97-codec snd-pcm snd-rawmidi snd-timer snd-seq-device snd-page-alloc" to SUSPEND_MODULES="$SUSPEND_MODULES <modules>" in a file in /etc/pm/config.d/ because i had worked with my wireless driver, but that didn't help. -- snd_cs46xx does not work after suspend/resume cycle https://bugs.launchpad.net/bugs/11149 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
