I discovered a curiosity: $ play ~/tmp/44100hz.wav $ ./list_devices playback device: 44100 Hz Built-in Audio Analog Stereo (default) $ play ~/tmp/48000hz.wav $ ./list_devices playback device: 48000 Hz Built-in Audio Analog Stereo (default) $ play ~/tmp/99999hz.wav playback device: 44100 Hz Built-in Audio Analog Stereo (default) In other words, PulseAudio changes the default sample rate of my playback device when I open it with a different sample rate. But if I open the playback device with a weird sample rate such as 99999Hz then PulseAudio changes the default sample rate to 44100Hz. When I say default sample rate, I mean when I query for the list of sinks with the API and look at the sample_spec. I'm trying to understand this phenomenon. Can anyone shed some light on this? -------------- next part -------------- An HTML attachment was scrubbed...
