gain. Beyond -42dB you can barely hear anything from the speakers, and I note that all my other systems only go down as far as -46.5dB.
This is normally just a case of drivers exposing whatever control they get from the hardware. Devices will often expose very high degrees of attenuation since they're doing it anyway in order to implement the mute functionality.
Yep. There are some workaround for each codec chip. See create_controls_idx() in patch_sigmatel.c, for example.
Great. Do you have any other examples? This does not seem so easy for a non-virtual master.
This is my kcontrol for master: HDA_CODEC_VOLUME("Master Playback Volume", 0x10, 0x00, HDA_OUTPUT),
Thanks, Daniel
