There are a few ways. If you build your kernel with SND_HDA_INPUT_BEEP_MODE=2, or set the option of snd-hda-intel module beep_mode=2, you'll be able to switch to the native beep from HD-audio codec digital beep via muting "Beep" mixer switch. Or, if the value above is 0, it'll be always the system-native beep. This can be done also via writing sysfs codec hint, as documented in HD-Audio.txt. Alternatively, you can reload pcspkr module so that it grabs the beep output again over snd-hda-intel, "modprobe -r pcspkr; modprobe pcspkr" Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
