What do you mean "front" in this context? Is it the front 2 channels out of 4.0 or 5.1 output? Or do you mean the physical location of the output? Front/Surround/Center/LFE are the former case. They are controls independent from the physical output locations (per definition). I guess this confusion came up because of the mix-up with front channel and front panel. We've used "Front Mic" in some places, for example, which increases the confusion. > PulseAudio assumes that if > a control is named "Front", it does just that.

Yeah, the output with your first patch would be helpful. thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
