[PD] PD on RaspberryPi – cheap multichannel sound-card

[Martin Recker]

Dear List,

For my current project I need a under 150€ multichannel Soundcard with 6 outputs and one input (line or mic). I already testet two link1 <https://www.ebay.de/itm/154839497111?chn=ps&norover=1&mkevt=1&mkrid=707-134425-41852-0&mkcid=2&itemid=154839497111&targetid=1267714667747&device=c&mktype=pla&googleloc=9042983&poi=&campaignid=10203814758&mkgroupid=119187115421&rlsatarget=pla-1267714667747&abcId=1145991&merchantid=138411352&gclid=CjwKCAjwtIaVBhBkEiwAsr7-c6rXaTChftlnGe8Cn_E-K62a-JtqEJvfbMA6rfMll-OtY1bMzoUHGRoCByoQAvD_BwE>, link2 <https://www.amazon.de/Terratec-Aureon-externe-Soundkarte-108dB/dp/B00ABB6U1G/ref=asc_df_B00ABB6U1G/?tag=&linkCode=df0&hvadid=407439622278&hvpos=&hvnetw=g&hvrand=11512454064301822034&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9060705&hvtargid=pla-916004115277&th=1&ref=&adgrpid=93934752224>) the latter has a better signal to noise ration, but both share one problem: The Inputs and Outputs show up as two different devices on raspberry and do not sync in the soundcard itself.

So two questions:

1. Can anyone recommend a suitable audio interface for under 150€, that connects as one device for input and output available in Germany?

2. Does anyone have recommendations to create a stable and reliable(!) aggregate device on raspberry to sync input and output on software side?


Thanks for any tips and thoughts!

Cheers,
Martin
