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.
Afaik Focusrite Scarlett audio interfaces usually work fine with Linux. Personally I have used the 2i2 gen 1, solo get 2 and 6i6 gen 2, all with my laptop running Ubuntu Studio and a Raspberry Pi.. I did try once a 18i20 with my laptop but couldn't get it to work (though I tried for a few minutes only as I was in the store selling the device). If you can get a 18i20 to work, you could have your system work I guess. Though it should cost a few hundred dollars, euros, or whatever. Still these are quite cheap priced devices.

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

usually you do not want to do this.
you would have to synchronize the clocks of the two devices (unless you into glitch). devices that allow simple synchronisation would use something like wordclock. but that is typically in a different price segment)

OTOH in this particular application you migth be able to run several Pd processes, one for each audio device, and sync them using netsend/netreceive. (Me, I use the startech "7.1" interface that costs about $25; the "1" is full bandwidth so it gives you 8 independent channels out. But I haven't tried two of them on the same pi; I just used multiple pis when I wanted to do a multichannel installation).

How many are 'many' :-)
If it's <= 8 channels and you don't care (too much) about latency you could check out a cheap '7.1' USB card (these can cost less than 30 euro online) and if it exposes 8 writable inputs via jack that could work. The physical outputs of these are, of course, unbalanced and in couples so you'd need to do some cable splitting and then maybe have a mixer nearby... I never did this on the RPi but I _did_ something similar with a cheap 5.1 usb sound blaster hooked to a laptop in the past. I'm assuming, of course that each file would 'consume' just 1 channel...
YMMV.
If you want more than 8 output channels it will be hard to stay 'cheap' (which of course depends on 'how much' is your limited budget), and then
'class compliant'...)
My two cents,
Lorenzo.
Thank you all for your replies. I didn't even know surround soundcards existed. This looks promising given my budget. In the meantime I found this : https://shop.audioinjector.net/detail/Sound_Cards/Octo+RCA+sound+card Anybody has experience using it with Pd ?

no really, but their other (stereo) card works great! https://dernulleffekt.de/doku.php?id=puredata:main https://dernulleffekt.de/doku.php?id=puredata:main

Hello,
I bought one octo for a project thanks to Thomas experience, It worked great at home when I plugged it on my mix table, but when I install everything in the project final destination, plug the sound-card on an amplifier, switch everything on: the sound card did not works anymore. I tried to contact someone at audioinjector, but I hardly have answer to my question. IT'S THE WORST CUSTOMER SERVICE EVER! It's been 2 week, my project is on standby, I'm still stuck with a broken sound card. So I don't recommend this soundcard to anyone and I consider buying a gigaport instead and throw this crap away.
unless someone have a suggestion to a cheaper 8 output soundcard for a RPI 4.
Cheers C
