Hey! Using the pisound so far only to stream music to my monitors using volumio which works perfectly. Now I am trying to use it to listen to it using the input TRS jacks and somehow I don’t hear anything. The red led is lighting up as expected. I have installed pisound-config and changed output t…

Okay, I had to investigate a lot further and this is a common problem for headless systems. My problem now is that it works when I start it manually with the user pi but when I make a bash script which gets triggered by pisound-btn I get the same error as before. I tried to add everything as in my…

Yes! Also would love to record it on the way.

There’s multiple ways to achieve the same: Use a command like: arecord -D hw:pisound -c 2 -r 48000 -f S16_LE | tee recording.wav | aplay -D hw:pisound - or use Audacity for graphical user interface (latest version(s) are known to have an issue when recording and playing back at the same time: Aud…

Uhm… so in the first place I‘d like to hear the sound. So when I understood correctly that is achieved by the aplay command. So when I want to hear something I put that command best to the pisound button? This is not working for me unfortunately … also it breaks everything else and I can‘t even ctr…

Ok, now that you start to define the problem you want to solve, we can get closer to finding the right solution for it. :slight_smile: The most seamless way then would be to have a JACK server running in the background all the time, forwarding data from input to the output, and a script for the but…

I haven‘t implemented the button - just used aplay command over ssh. Volumio „OS“ is running and aplay also broke output of volumio / Spotify / airplay which I‘d like to keep at all times. edit: Okay … aplay now stopped and Spotify works again - I could live with that happening if it comes back on…

Then you have to find a way to pipe through the input of Pisound to the output in a way that is friendly to all the software you want to keep running. I don’t know about the audio backends that are used by the listed software… A virtual audio loopback device ( https://www.alsa-project.org/main/index…

Sorry but this solution seems a bit too intense for me right now. Your aplay command is not working because it needs to have a file, right? It‘s not routing anything. Would be nice to route the audio in to the audio out for a starter… as I said I would be fine with not being able to use streaming …

aplay and arecord commands take exclusive control of the hardware, so stop any background applications which are working with sound before running them. To record to a file and play it back at the same time, run: arecord -D hw:pisound -c 2 -r 48000 -f S16_LE | tee recording.wav | aplay -D hw:pisou…

Ah, okay! Works - thanks! - but unfortunately it adds a loooot of latency - I play live music so this is unacceptable. So I guess I need to take the jackd route now…

JACK is the route for low latency audio. I’d recommend using MODEP image for this then.
