No sound after hibernate

algogeek · 08-11-2008, 05:13 AM

Hello, I've been facing this problem since the early releases of Fedora, and it still doesn't seem to have been rectified. I have uploaded the alsa-info information here, and would like to know what is wrong and the workaround.

My system's sound does not work after hibernating. It works well after a fresh reboot though.

Perhaps unloading the sound-modules before hibernate, and reload them after un-hibernating?

How? .

You have to look at the docs of your distro. For me it's "modprobe -r <modulename>" to unload the drivers and "modprobe <modulename" to load them. It might as well be "insmod". And you can get the list of the currently loaded drivers/modules with "lsmod" - install it if you don't have it - the package might be called something like mod-utils or something like that.

Thank you. I hope that solves my problem, it sure does sound effective. Thanks again.

You're welcome. And the docs of suspend/hibernate specify this explicitly (you have even a configuration section where to put the names of such modules). And it worked in my case. Good luck.
