I tested with rec (sox program) with firefox configured to use OSS. Last bug report is the following: suspend to s3 is broken when some music is being played. Before your changes there was a end less loop of pcm_unregister waiting on pid so technically it was already broken. After your changes, I can see the firefox tab playing something being killed, and the pcm_unregister is not complaining anymore. I can see the screen being switched to vt but then nothing is printing on the screen, but I can here the fan starting spinning like crazy :( If I don't play music, suspend/resume works properly Best regards, Bapt
