Hi, in my setup I have a Raspberry with an old USB soundcard as a RTP sender and an old netbook as the RTP receiver. I use the netbook to connect a bluetooth speaker to it. If important: this is unicast RTP. If I start streaming music on the sender side, it takes a long time until I get output on the receiver side (with "long" I mean magnitude of: several seconds, up to minutes), and also the "pitch" of the music is audible lower / slower than what I can hear on the sending device. Troubleshooting steps so far: If I start the pulseaudio daemon on the sender side (with module-rtp-send), then on the receiver side, I get this message in the log (about every 5 seconds): "Sample rates too different, not adjusting (44100 vs. 57567)." The 57567 value slowly increases in time. I also noticed that on the receiver side, the sink-input "Buffer Latency" quickly increases over time, as seen here for example: ~$ pactl list sink-inputs Sink Input #0 Driver: module-loopback.c Owner Module: 7 Client: n/a Sink: 1 Sample Specification: s16le 2ch 44103Hz Channel Map: front-left,front-right Format: pcm, format.sample_format = "\"s16le\"" format.rate = "44100" format.channels = "2" format.channel_map = "\"front-left,front-right\"" Corked: no Mute: no Volume: front-left: 65536 / 100% / 0.00 dB, front-right: 65536 / 100% / 0.00 dB balance 0.00 Buffer Latency: 135137 usec Sink Latency: 69810 usec Resample method: speex-float-1 Properties: media.role = "abstract" media.name = "Loopback from Monitor of NullSink" media.icon_name = "audio-input-microphone" Sink Input #1 Driver: module-rtp-recv.c Owner Module: 10 Client: n/a Sink: 0 Sample Specification: s16be 2ch 44100Hz Channel Map: front-left,front-right Format: pcm, format.sample_format = "\"s16be\"" format.rate = "44100" format.channels = "2" Corked: no Mute: no Volume: front-left: 65536 / 100% / 0.00 dB, front-right: 65536 / 100% / 0.00 dB balance 0.00 Buffer Latency: 13670815 usec Sink Latency: 6885 usec Resample method: speex-float-1 Properties: media.role = "stream" media.name = "RTP Stream (PulseAudio RTP Stream on raspberrypi)" rtp.session = "PulseAudio RTP Stream on raspberrypi" rtp.origin = "pi 3864408555 0 IN IP4 192.168.2.30" rtp.payload = "10" ~$ Here the "Buffer Latency" is already almost 14 seconds, this is only shortly (1-2 minutes) after a restart of the daemon. Any idea on how to either solve this quick and dirty, or troubleshoot further?
Update: I tested the setup with module-null-source on the Raspberry (RTP sender) side - this works without problems. I think this is some weird clocking issue, maybe exposed by the combination of Raspberry + ancient usb Soundblaster sound card. tsched on or off does not make any difference, also the system time is set by ntp and looks fine...
