HI everybody,
I have this problem since quite some time now.
On my HP laptop I am using Gnome 3, started via gdm. I get frequent system freeze on it, and I am not sure what triggers them.
Freezes happen after the system is started, on boot right after systemd is finished starting services but before X is on, and on shutdown at stopping sound card device.
This lead me to think that it may be an audio problem, and indeed disabling pulseaudio solves every issue.
However, since pulseaudio is very nicely integrated with Gnome, I would like to use it if possible.
Do you have any ideas what could cause the system freezes, and how can I fix pulseaudio in order to avoid them?
I believe it could be related to the fact that there are two sound cards on the machine, one of them being a high definition card somehow connected to the discrete ATI graphic processor. Since I use only the integrated Intel, I usually turn off at boot the ATI graphics. I always thought this would turn off also the high definition audio, but I do not really know how to check that.
Do you guys have any suggestions on what I could do to fix the problem?
I don't have the HP laptop with me at the moment, but if you tell me what kind of logs you need to see I can provide them later in the day.
Thanks in advance!
