What options do I have when it comes to embeddind sound card in my design ? I want input/output >=22KHz mono (voice and FAX)
I found PCM2906, DS4201 and few alike, but its USB, and I have no USB in my design, only bunch of GPIO pins or memory mapping.
All that I can think of is connecting old ISA sound card to my board. Are there any modern options ?
Pozdrawiam.
