Hello all! I'm using OpenBSD 7.2 RELEASE, but I've seen this problem on earlier versions as well. Please tell me, when I am playing audio through sndio, for example with firefox or mpd, and the processor load starts to increase, for example because I opened a heavy web page or some heavy application, sometimes I hear clicks, or my audio is interrupted, and I have to restart the playback. I can see in the mpd log at this time:
output: Failed to play on "Libao Audio Device" (sndio): sndio write failed I tried increasing the sndiod buffer to 9600, but that didn't do anything. I also tried running sndio with the -d flag, but I didn't see any errors. I have two laptops with OpenBSD, a Thinkpad x250 and a Latitude 5300, and both laptops have this problem. If anyone can tell me what might be the problem, I would be very grateful, thank you very much.
