Hi, I'm trying to stream some bluetooth audio via ethernet to another pulseaudio server. I'm using module-tunnel-sink-new with TCP connection. On the sender computer I have a bluetooth stream generating a variable bit rate sink-input (around 44.4KHz on average), which I then move to the tunnel sink with 44.1KHz sample rate. What I noticed is the audio on the receiver side would stutter every ~6 seconds, and it's very consistent. And when it stutters, I observe the following log on the sender side: (15031.656| 0.351) I: [tunnel-sink] module-loopback.c: Could not peek into queue (15031.664| 0.007) I: [tunnel-sink] module-loopback.c: Could not peek into queue (15031.672| 0.008) I: [tunnel-sink] module-loopback.c: Could not peek into queue (15031.680| 0.007) I: [tunnel-sink] module-loopback.c: Could not peek into queue (15031.688| 0.008) I: [tunnel-sink] module-loopback.c: Could not peek into queue (15031.696| 0.007) I: [tunnel-sink] module-loopback.c: Could not peek into queue (15031.704| 0.007) I: [tunnel-sink] module-loopback.c: Could not peek into queue (15031.712| 0.007) I: [tunnel-sink] module-loopback.c: Could not peek into queue (15031.720| 0.008) D: [pulseaudio] module-loopback.c: Underrun detected, counter incremented to 6 And then the sample rate would change. I tried the following: - Changing sampling method doesn't seem to make a difference. - Tried moving the bluetooth stream to a local sink with 44.1KHz sampling rate, and no stutter was observed. - Tried adding --realtime=yes and --high-priority=yes options on the sender pulseaudio server, no difference. - Tried creating additional remap sinks between the bluetooth stream and the TCP tunnel sink, no difference. - Tried moving a constant bit rate stream of 44.1KHz to the tunnel sink, no stuttering was observed on the receiving end. I'm wondering, is this caused by some weird interaction between resampling and the tunnel sink? Any suggestions how this kind of problem can be debugged?
