[Feature Request] USB audio device #1

Closed buldo closed 8 months ago

buldo commented 1 year ago

Is it possible to use usb device mode to receive audio from pc via usb on overclocked rpi zero?

TudbuT commented 1 year ago

Most likely, but I don't know how USB audio works so im not qualified to add it at this moment.

TudbuT commented 1 year ago

I thought a bit: I think one might be able to stream the audio over UART, but I don't think it'll be very good quality, and it might be hard to transmit and receive fast enough.

My original idea was use tinyUSB. So rpi pico will act as usb sound card. BTW, my feature request is more fun idea, than "I really need this and will use every day"

Using USB to play audio is now supported by pico_gpio using the following command: 

( echo ; echo pwmfreq 1557000 ; echo audiostream 0 ; echo -en "\x80" ; pacat -r -d @DEFAULT_MONITOR@ --rate 111000 --format u8 --channels 1 --raw ) | pv -rK | picocom /dev/ttyACM0 -n
