There is a GPIO pi zero soundcard to be released soon by an Australian company called Audio Injector:

http://www.audioinjector.net/rpi-shop

I have used their stereo card on my PI2 & 3 with great results. . . very low latency (below 4ms!).

Also they have a 16 channel card (8in/8out) which is very tempting.

I can also recommend this very cheap thing here (around 8€):

(I think both are more or less the same).

the latency is quite bad but basically the same as the Behringer UCA202. I used it several interactive installations with the Raspberry Pi 3 where I didn't need ultra low latencies and it worked well.

Betreff: Re: [PD] pd on pi zero ?

I got smooth audio stereo output (didn't test input) with a Behringer U-Control UCA202 and a pi-zero.
I just tried a simple sine wave, I didn't push it to see what happens under load...but now I'm curious to revisit it and see...

I would think Pd should work on a zero, though I haven't tried it myself.
 
Miller has some sound card recommendations on the Pd documentation http://msp.ucsd.edu/Pd_documentation/x3.htm#s1.0[http://msp.ucsd.edu/Pd_documentation/x3.htm#s1.0] in the section "Audio hardware in Linux".
 
I have had good luck with the Griffin Technology iMic with the non-zero Raspberry Pi models - amazon.com/gp/product/B003Y5D776[http://amazon.com/gp/product/B003Y5D776], and I think it's based on one of the chipsets that Miller found worked well.

i have successfully used the PhatDAC and other I2S based dacs. Output-only though!
Will report later on trying the audioinjector octo card which is input/output.
best, Thomas
