It's interesting whether the sound > is resumed well with snd-opl3sa2 driver. I remember it worked quite > ago, but not tested with the recent versions. My machine can sleep but not hibernate. After sleep the sound is resumed well. I also edited cs4231_lib.c and changed lines 242 and 861 from "#if 0" to "#if 1" (thus enabling the call to snd_cs4231_debug(chip) at the end of snd_cs4231_playback_prepare() ). Here is the output I got: 1. module opl3sa2 a.
