Audio output is muted on Ubuntu

[bi3mw]

I have started the swradio-9-x86_64.AppImage on Ubuntu 22.04. Unfortunately the audio output is muted ( setting "default" ). What could be the reason for this ?

The selection "default" seems to be the correct one, because the ALSA plugin [swradio-9] appears in the list under "Sound". Nevertheless, there is no output to the speakers.

When I start the program in the terminal, I get the following output:

Api 0 is ALSA

Api 1 is OSS

Api 2 is JACK Audio Connection Kit

The wau it is implemented is that on program startup, the portaudio library is initialized. That library does the talking to Alas aor whatever your sound system is and returns a list (as you have shown) of channels that are supposed to be audio channels for 48000 bd output. In your case it seems that portaudio has some problems with your system. The only thing I can say is that on my Fedora box and the Ubunu box it functions Op wo 3 jan 2024 om 15:29 schreef bi3mw ***@***.***>:
