no its just controlling how much gets through. on the audiophile "amixer scrontrols" gives you something like this: Simple mixer control 'DAC',0 Simple mixer control 'DAC',1 Simple mixer control 'Multi',0 Simple mixer control 'Multi',1 Simple mixer control 'Multi',2 Simple mixer control 'Multi',3 Simple mixer control 'Multi',4 Simple mixer control 'Multi',5 Simple mixer control 'Multi',6 Simple mixer control 'Multi',7 Simple mixer control 'Multi',8 Simple mixer control 'Multi',9 Simple mixer control 'Multi Track IEC958 Master',0 Simple mixer control 'Multi Track Peak',0 Simple mixer control 'Multi Track Volume Rate',0 while on a card with the ak4524 (like the Delta 44) you get something like this: Simple mixer control 'ADC',0 Simple mixer control 'ADC',1 Simple mixer control 'ADC',2 Simple mixer control 'ADC',3 Simple mixer control 'DAC',0 Simple mixer control 'DAC',1 Simple mixer control 'DAC',2 Simple mixer control 'DAC',3 Simple mixer control 'IPGA Analog',0 Simple mixer control 'IPGA Analog',1 Simple mixer control 'IPGA Analog',2 Simple mixer control 'IPGA Analog',3 Simple mixer control 'Multi',0 Simple mixer control 'Multi',1 Simple mixer control 'Multi',2 Simple mixer control 'Multi',3 Simple mixer control 'Multi',4 Simple mixer control 'Multi',5 Simple mixer control 'Multi',6 Simple mixer control 'Multi',7 Simple mixer control 'Multi',8 Simple mixer control 'Multi',9 Simple mixer control 'Multi Track IEC958 Master',0 Simple mixer control 'Multi Track Peak',0 Simple mixer control 'Multi Track Volume Rate',0 the important bits are the "IPGA Analog" controls. These only show with an ak4524 ADC. christof -- Christof Damian Technical Director, guideguide ltd. _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
