What chip is available for a audio channel select and volume control ? Some chips are hard to get.
I have made a FM radio with the TEA5767 (noisy, not sensitive, medium sound quality), but now I want to combine it with other audio sources. I want to select between 4 sources but a mixer for all channels would very nice, or else just one volume control.
The CD4066 could be good enough to select the channel. But I also need a volume control. The quality has to match the good quality of my computer soundchip (ALC889A). What chips are available ?
