Sound in VLC/Chrome/Firefox/Parole pauses or resumes after every 5 seconds. However, it works fine using aplay and paplay. VLC log:

I have straced both working paplay and non-working cvlc, both seem to use /run/user/1000/pulse/native. However, a strace of cvlc shows this when the pause/resumes toggles (fd 10 is /run/user/1000/bus):
[pid 30556] 21:54:04 recvmsg(10, {msg_namelen=0}, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable)
The sound card is a "Dinto" USC-C dock with built in sound. My other sound card works fine.
How to debug further? PA sinks:
