![]() ![]() Is this with BUFSZ_P2 disabled like ports 27f51d17e156 requires? (In reply to Sean Farley from comment #0) > On my system, the CPU usage hovers around 70%. For me CPU usage is around 10% in foreground (current workspace) and 5% in background (different workspace). In both cases music is still playing, and I don't see "underrun occurred" ALSA warnings. Tested under sway-devel. (In reply to Jan Beich from comment #1) Actually, no. My options were: BLKCNT_P2: on BUFSZ_P2: on FFMPEG: off JACK: off PULSEAUDIO: off SAMPLERATE: off SPEEX: off VERBOSE: off However, aplay worked for me for 16- and 32-bit WAV files but not the 8-bit file. $ aplay /usr/local/lib/python3.9/test/audiodata/pluck-pcm16.wav Playing WAVE '/usr/local/lib/python3.9/test/audiodata/pluck-pcm16.wav' : Signed 16 bit Little Endian, Rate 11025 Hz, Stereo $ aplay /usr/local/lib/python3.9/test/audiodata/pluck-pcm8.wav Playing WAVE '/usr/local/lib/python3.9/test/audiodata/pluck-pcm8.wav' : Unsigned 8 bit, Rate 11025 Hz, Stereo Assertion failed: (err >= 0), function set_params, file aplay.c, line 1399. Aborted by signal Abort trap... Apparently, that option was the issue. I disabled both *_P2 options, and it is now stable. Thank you very much! I probably kept them enabled when they were switched back and forth a few times. Out of curiosity, is there any use for those two options? I also want to mention that with these options disabled, wine-devel can now play sounds when it could not with these options enabled. I do see a few underruns in wine-devel running https://github.com/BlueDragon28/MicrophoneLoopback, with ALSA_OSS_BUFSZ_MAX at either value. However, it does work now, so that is a good thing.
