No patch needed... I've made the suggested change and it works identically. I still need to make a similar change in mixer_volume_to_db() and get the value of my MAX_MIXER_ATTENUATION_DB constant out of ALSA , even though this is an unchanging aspect across all ICE1712 chips per architecture: http://nielsmayer.com/envy24control/envy24mixer-architecture.png #define MAX_MIXER_ATTENUATION_DB 144.0 /* for -144dB */ #define MIN_MIXER_ATTENUATION_DB 0.0 /* for 0dB */ /* NPM: the control values for the digital mixer are 0-96 and not the dB attenuation values of MAX_MIXER_ATTENUATION_DB/MIN_MIXER_ATTENUATION_DB The following values comprise all the signals mixed in the ice1712's digital mixer: MULTI_PLAYBACK_VOLUME, HW_MULTI_CAPTURE_VOLUME, IEC958_MULTI_CAPTURE_VOLUME: > amixer -c M66 cget iface=MIXER,name='Multi Playback Volume' numid=11,iface=MIXER,name='Multi Playback Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=96,step=0 : values=78,67 | dBscale-min=-144.00dB,step=1.50dB,mute=0 > amixer -c M66 cget iface=MIXER,name="H/W Multi Capture Volume" numid=27,iface=MIXER,name='H/W Multi Capture Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=96,step=0 : values=0,0 | dBscale-min=-144.00dB,step=1.50dB,mute=0 > amixer -c M66 cget iface=MIXER,name="IEC958 Multi Capture Volume" numid=31,iface=MIXER,name='IEC958 Multi Capture Volume' ; type=INTEGER,access=rw------,values=2,min=0,max=96,step=0 : values=16,0 */ -- Niels http://nielsmayer.com _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
