No sounds comes

[tizfra]

Hi, I've update my squishbox to version 0.7.12, but now no sounds comes out.
Midi messages arrives correctly to squishbox and also isn't a hardware sound module problem, because i've tryed to reinstall fluidpatcher to my squishbox using raspberry headphone jack and no sounds comes out.
@albedozero if you need more information, tell me what you need.

Hmm.. I haven't found a bug yet. Can you send the squishboxconf.yaml and bank file that you are using?

[tizfra]

Yes of course
squishbox.zip

[albedozero]

You can probably remove the line synth.audio-channels: 16 from your squishboxconf.yaml. It was in there for effects routing, but newer versions don't need it.

Also, I noticed you have a high synth.gain value set in your bank8.yaml - values above 1.0 can produce some unwanted distortion. If you're trying to get louder audio output you can try turning up the volume using alsamixer at the command line.

How can I turning up volume in alsamixer? I've tryed but on sound card snd_rpi_hifiberry_dac tells me that this sound decice does not have any controls.

I may have figured it out - Recently after a lot of testing I decided to switch from using the JACK driver (audio.driver: jack) and use the default ALSA driver. JACK is meant to provide fast communication when you have multiple audio applications at once, which is not the case in the SquishBox, plus it adds an unnecessary extra layer of processing overhead. However, the installer wasn't automatically making this switch for users who installed using an older version that uses JACK.

To fix, run the installer (which I just updated), and for the question "Which audio output would you like to use?" choose sndrpihifiberry if you want to use the SquishBox's 1/4" outputs, or Headphones if you want to use the physical headphone jack on the Raspberry Pi. You can answer no/no change for the other questions.

You could instead do this manually by changing the line in your squishboxconf.yaml

  audio.driver: jack

to

  audio.driver: alsa

I have also some problems with the new way.
I have a compleet new installation.
With a usb audio (Dragonfly) stick.
i have checked with the alsamix to volume and is it's umuted.

Pre versions did work out of the box.

I assume you are getting no sound when you play on your connected MIDI keyboard? It could be you have modified the wrong config file - fluidpatcherconf.yaml is the config file for the desktop program fluidpatcher.pyw. If you are running squishbox.py or headlesspi.py they both use squishboxconf.yaml, which is in the SquishBox/ directory.

Oh thanx that's explaining a lot. I have trying tot get it work it will only work on my headphones. So that's a step.

I will try today investigate the usb audio dongle to get it work.

Any results I will post here.

[j-vanwijk]

I can get it to work.
I had some problemen with latency to get fluidsynth to work. My Drangonfly usb stick has some optimal Sample rates so the Raspberry pi CPU is offloaded. With "fluidsynth -a alsa -o audio.alsa.device=plughw:1,0 -m alsa_raw -o "midi.alsa.device=hw:0,0,0" sf2/piano/Kawai\ Upright\ Piano.sf2" I have get Fluidsynth to work nicely

for now it's for me fine. I've i got some spare time i can look howto get it work with the fluidpatcher and Alsa.
