I'm not sure this is the same bug, but at least it is similar. I've decided to copy some cassettes using an USB deck, so I try to use Audacity without any previous experience with the program and generally with no experience in sound processing.
Unfortunately I have no sound on the playback independently of the playback device chosen. I have 5 options: HDA Intel HDMI: 0 (hw:0,3) HDA Intel HDMI: 1 (hw:0,7) HDA Intel PCH: AL270 Analog (hw:1,0) HDA Intel PCH: AL270 Digital (hw:1,1) hdmi default On the other hand the sound control panel shows: HDMI / DisplayPort 2 - Build-in Audio Digital Output (S/PDIF) - Built-in Audio Speakers - Built-in Audio For information, on the same computer on Windows 10 Audacity works without problems, the playback choice are (in Polish): Mapowanie dźwięku ...
