Hi, 

Pd under works with any sound card supported by Linux.
One good and cheap option is the ESI Gigaport HD+ which provides 8 analog output for less than 200€.
I successfully test this card on Raspberry Pi few years ago.
Nowadays with RPi4 and its upgraded USB and ethernet chipset you could even think plugin 2 of them on the same board.

There might be also some other option.

Cheers

Dear all,

I haven't posted anything on this list in years.
I'm trying to build a system to play several sound files in a loop,
each around 2 minutes in length, all at the same time. By "several" I
mean 10 to 15 different files. While I'd have no problem making a Pd
patch to achieve this, I have no idea what hardware I could use. I
have a limited budget, and I was planning on running Pd on a Raspberry
Pi (or similar single-board computer).

Is there any cheap way of outputing than many channels from a single
(a couple of) RPi ?

Thanks in advance,

Pierre.
