If I play my AC3 data on my HDAudio/SPDIF output using the hw:0,1 device, I can use alsamixer/amixer to mute/unmute. [ume@plb PassThough]$ amixer cset numid=12 on numid=12,iface=MIXER,name='IEC958 Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on [ume@plb PassThough]$ amixer cset numid=12 off numid=12,iface=MIXER,name='IEC958 Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=off Now if I use the iec958: plugin, I can't control the mute switch any longer: [ume@plb PassThough]$ amixer cset numid=12 off amixer: Control default element write error: Operation not permitted [ume@plb PassThough]$ amixer cset numid=12 on amixer: Control default element write error: Operation not permitted What could possibly cause this issue? the IEC plugin relies on the device 1, am I missing something here?
