Hi, I will not quote the earlier messages as I found new way to generate this buzzing sound (for debugging).
Works both for 14.4-RELEASE (I downgraded to that for less sound issues) and latest 15.1-RELEASE. Start playing some MP3 with 'audio/deadbeef' player - I tried both PulseAudio and OSS backends - same behavior - You need to compile Deadbeef from ports if You want to have PulseAudio backend. Next install 'benchmarks/glmark2' and run it without any other parameters with 'glmark2' command. First benchmark is 'rotating horse', second is 'rotating crate box' - buzzing will start at the end of 'horse' and will continue on the 'box' and rest of the benchmarks. Setting these change nothing: # sysctl hw.snd.timeout=0 # sysctl hw.snd.latency=0 Bug submitted here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=297059 Regards, vermaden
