Can't use RPI audio receiver (Bluetooth)

[Xitee1]

I have installed MLSC on my Raspberry Pi with this https://github.com/nicokaiser/rpi-audio-receiver programm so I can send the data with Bluetooth to the RPi. I have selected the "microphone" (BL audio). I have a ESP8266 with WLED connected with MLSC which is working just fine with the Non-Music effects. However if I want a Music-Effect the connection to WLED times out (I think - the light pauses and stays on for a few seconds until it goes off and WLED is no longer saying that it is used through the API). Can anyone help me?

I have changed debug from info to warning and now there is an error in the console:

Hi,

looks like an issue with pyaudio and your music/input source. Does this error occurs, if you use the default device?

[Xitee1]

Yes, it also occurs if I use the default device. But I have just bought me a USB sound card and an aux splitter for the music input. It's better anyways because there is less delay.

i have the same problem ( with the pi3) i try to config a virtual mic at the moment , unfortunately unsuccessful so far

[TobKra96]

Yes, virtual mics are hard to config and buggy at the moment. At the moment I could not find a solution for virtual mics.
