Hi John, this suggests you've got PulseAudio running rather than PipeWire. Tom MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

I have, yes. Would pipewire be better? I seem to have OK sound but don't know if it could or should be better. John |

John, If you have a working system then I wouldn't mess with it ;-) My confusion arose from: 1. In this post you said you had pipewire installed but "wire" did not appear in the grep results: https://www.thebackshed.com/forum/ViewTopic.php?TID=17635&P=1#232895 2. But then in your latest post you said you were using pulseaudio: https://www.thebackshed.com/forum/ViewTopic.php?FID=16&TID=17635&LastEntry=Y#232905#232905 I think we have confirmed that (a) you have pulseaudio, not pipewire, and (b) it is working.

@Tom, The laptop uses pulse audio. But apparently alsa is needed to get sound. Maybe this version is too old (13.99.1). harm@harm-Latitude-E7450:~$ ps -axuww | grep -e pulse -e wire harm 923 0.0 0.2 1409068 19440 ?

Hi @Volhout, <shrugs shoulders> I'm not qualified to support 'pulseaudio' ... I'm not sure how to even easily test whether it is working/configured properly on your laptop of not, and my laptop is running pipewire (which I don't want to break) so I've no easy way to play myself. I guess your options are live with ALSA (if it works don't try and fix it), or you go off into the wilds of Linux support on the web to see if (a) you can find out how to test if pulseaudio is working correctly at all, and (b) if not, then how to fix it. Apologies that this might not be the level of support you are looking for but it's the best I can offer, Linux is a lot more complex a platform than a micro-controller  .Best wishes, Tom MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Tom, Sorry for the confusion. Seems they're both installed and pulseaudio is running. I know essentially nothing about either of them! John |

Me neither, like so much of Linux it's both a black box and a constantly moving target. @matherp, don't think I can't hear you sniggering  .Best wishes, Tom MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Hi Tom, I will just use ALSA. No problem.... Volhout PicomiteVGA PETSCII ROBOTS |
