Rhasspy recognizes microphone but only reads 44 bytes of data #196

I've got a fresh rhasspy git/venv installation on my RPi 3B. I use a PlayStation Eye as microphone. When I test the microphone in the "Speech" tab in the web interface, I get the following error in the command line running rhasspy:

Interestingly, when testing my microphone with arecord I get a similar error as the resulting file also contains only 44 bytes. This is the output:

Also, during startup, I get the following errors (but don't know, whether they do any harm):

I don't know what all the pulseaudio errors mean. I had pulseaudio installed once, but removed it from my system. Might this be an issue?

synesthesiam commented 4 years ago

44 bytes is the length of the WAV header, so it's getting no audio samples. What do you see when you run the microphone test in settings?

moritzschaefer commented 4 years ago

My .asoundrc wasn't configured correctly which caused this issue. Sorry for the inconveniences.
