I’m currently using the WaveIn plugin to play incoming audio (echo dot) from a USB stick. I’ve adjusted the buffer Threshold of the wavein plugin to 20kbyte and it works pretty fine at first, however the longer the wavein plugin works, the longer the delay of the output audio gets. All the way to an 8 second delay, whereas at first it is below a second.
Now, I’m looking for any information on how to fix or debug this issue.
I’m using arecord | aplay to pipe the USB output with small buffer-time’s to the pcm that I then read via the wavein plugin, so I don’t think that’s the issue.
