The volume in alsamixer *looks* the same for both channels, but "amixer contents" turns up the following: numid=24,iface=MIXER,name='Capture Source' ; type=ENUMERATED,access=rw---,values=2,items=8 ; Item #0 'Mic' ; Item #1 'CD' ; Item #2 'Video' ; Item #3 'Aux' ; Item #4 'Line' ; Item #5 'Mix' ; Item #6 'Mix Mono' ; Item #7 'Phone' : values=4,0 My reading of that is that "Line" is the Capture Source for the Left channel only, with "Mic" as the Capture Source for the Right channel. Is that correct?? Full output of "amixer contents" follows: ~$ amixer contents numid=5,iface=MIXER,name='Master Mono Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=off numid=6,iface=MIXER,name='Master Mono Playback Volume' ; type=INTEGER,access=rw---,values=1,min=0,max=31,step=0 : values=0 numid=1,iface=MIXER,name='Master Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=on numid=2,iface=MIXER,name='Master Playback Volume' ; type=INTEGER,access=rw---,values=2,min=0,max=63,step=0 : values=48,48 numid=3,iface=MIXER,name='Headphone Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=off numid=4,iface=MIXER,name='Headphone Playback Volume' ; type=INTEGER,access=rw---,values=2,min=0,max=31,step=0 : values=31,31 numid=30,iface=MIXER,name='3D Control - Center' ; type=INTEGER,access=rw---,values=1,min=0,max=15,step=0 : values=0 numid=31,iface=MIXER,name='3D Control - Depth' ; type=INTEGER,access=rw---,values=1,min=0,max=15,step=0 : values=0 numid=27,iface=MIXER,name='3D Control - Switch' ; type=BOOLEAN,access=rw---,values=1 : values=off numid=22,iface=MIXER,name='PCM Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=on numid=23,iface=MIXER,name='PCM Playback Volume' ; type=INTEGER,access=rw---,values=2,min=0,max=31,step=0 : values=25,25 numid=14,iface=MIXER,name='Line Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=on numid=15,iface=MIXER,name='Line Playback Volume' ; type=INTEGER,access=rw---,values=2,min=0,max=31,step=0 : values=26,26 numid=16,iface=MIXER,name='CD Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=on numid=17,iface=MIXER,name='CD Playback Volume' ; type=INTEGER,access=rw---,values=2,min=0,max=31,step=0 : values=0,0 numid=13,iface=MIXER,name='Mic Boost (+20dB)' ; type=BOOLEAN,access=rw---,values=1 : values=off numid=29,iface=MIXER,name='Mic Select' ; type=ENUMERATED,access=rw---,values=1,items=2 ; Item #0 'Mic1' ; Item #1 'Mic2' : values=0 numid=11,iface=MIXER,name='Mic Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=off numid=12,iface=MIXER,name='Mic Playback Volume' ; type=INTEGER,access=rw---,values=1,min=0,max=31,step=0 : values=2 numid=9,iface=MIXER,name='Phone Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=off numid=10,iface=MIXER,name='Phone Playback Volume' ; type=INTEGER,access=rw---,values=1,min=0,max=31,step=0 : values=0 numid=18,iface=MIXER,name='Video Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=off numid=19,iface=MIXER,name='Video Playback Volume' ; type=INTEGER,access=rw---,values=2,min=0,max=31,step=0 : values=0,0 numid=7,iface=MIXER,name='PC Speaker Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=off numid=8,iface=MIXER,name='PC Speaker Playback Volume' ; type=INTEGER,access=rw---,values=1,min=0,max=15,step=0 : values=0 numid=20,iface=MIXER,name='Aux Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=on numid=21,iface=MIXER,name='Aux Playback Volume' ; type=INTEGER,access=rw---,values=2,min=0,max=31,step=0 : values=31,31 numid=28,iface=MIXER,name='Mono Output Select' ; type=ENUMERATED,access=rw---,values=1,items=2 ; Item #0 'Mix' ; Item #1 'Mic' : values=1 numid=24,iface=MIXER,name='Capture Source' ; type=ENUMERATED,access=rw---,values=2,items=8 ; Item #0 'Mic' ; Item #1 'CD' ; Item #2 'Video' ; Item #3 'Aux' ; Item #4 'Line' ; Item #5 'Mix' ; Item #6 'Mix Mono' ; Item #7 'Phone' : values=4,0 numid=25,iface=MIXER,name='Capture Switch' ; type=BOOLEAN,access=rw---,values=1 : values=on numid=26,iface=MIXER,name='Capture Volume' ; type=INTEGER,access=rw---,values=2,min=0,max=15,step=0 : values=8,8 numid=32,iface=MIXER,name='IEC958 Playback Con Mask' ; type=IEC958,access=r----,values=1 : values=? numid=33,iface=MIXER,name='IEC958 Playback Pro Mask' ; type=IEC958,access=r----,values=1 : values=? numid=34,iface=MIXER,name='IEC958 Playback Default' ; type=IEC958,access=rw---,values=1 : values=? numid=35,iface=MIXER,name='IEC958 Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=off numid=36,iface=MIXER,name='External Amplifier' ; type=BOOLEAN,access=rw---,values=1 : values=on Adelle. ------------------------------------------------------------------------- Using Tomcat but need to do more?
