Latency: 103758 usec, configured 100000 usec There is currentlatency and configuredlatency present in every source and sink. You cannot configure latency directly but you can modify variables that affect latency positively. Modules and scheduling Several other Pulseaudio modules (other than just module-alsa-card) are present in this example setup.

The latency is an attribute of the sink. You can change it through anything that uses the Pulseaudio libraries. If you cannot use pavucontrol, you could use pacmd with set-port-latency-offset. If you cannot use that, either, please edit the question and explain what you can and cannot use in your situation.

To get an extra buffer you could add a null sink to use module-loobpack's latency_msec like so: pactl load-module module-null-sink sink_name=delayed pactl load-module module-loopback latency_msec=2000 source=delayed.monitor sink=alsa_output.pci-0000_00_1b.0.analog-stereo Then you have to combine the null sink with your bluetooth audio.

Latency problem when combining sinks (#15) · Issues ...

Either a huge latency (about a second) appears (this happens the most times) or pulseaudio uses 100% CPU and no sound is hearable (e.g. when playing something with audacious). The problem happens with the loopback and the combine-sink modules, I've tried both. Here are log messages from when it used 100% CPU: https://pastebin.com/raw/3B0R1ugr

[GUAC-427] Improve PulseAudio latency and bandwidth usage ...

https://jira.glyptodon.com/browse/GUAC-427

Description. The current experimental PulseAudio support of libguac-client-vnc sends constant audio data over the wire even when audio isn't playing (it encodes silence), using excessive bandwidth. There is also wide variance in latency, with anywhere from < 1 second to 5+ seconds. Both of these situations need to be improved to help PulseAudio support get out of its …
