And after some experimentation myself, it seems like this is a known bug: https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/822 It seems like the wav format does work, so give this variant a try: $ pacat -v -r --file-format=wav /tmp/sounds.wav and $ pacat -v -p --file-format=wav /tmp/sounds.wav > On a different file (created yesterday): > $ ffprobe -hide_banner test-mic.wav Input #0, wav, from 'test-mic.wav': > Duration: 00:00:16.00, bitrate: 64 kb/s > Stream #0:0: Audio: pcm_u8 ([1][0][0][0] / 0x0001), 8000 Hz, 1 channels, u8, 64 kb/ > and > $ pacat -p test-mic.wav > produced two clicks from the speaker. > > Found one potential issue: the Focusrite had the 'Air' button pressed under > the input volumn knob.

My Scarlett solo is an older gen, so it doesn't have an "air" switch. I was curious what that was, so here's what their docs have to say: >> An important feature of all 3rd Generation Scarlett interfaces is >> Focusrite’s exclusive AIR function.

Lol, it's just a fixed EQ curve. This should not be the cause of your issues, though feel free to use it if you like the tone it produces. --Sean _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
