Ubuntu Studio 20.10 sound card not picked up

Giorgio Zarrelli il giovedì, 25 Marzo, 2021

I got my PC hooked up to a kvm and I switch between my computers quite often. Connected to the kvm there are a bunch of peripherals: a keyboard, a mouse, a monitor and a Behringer U-Phoria sound card.

Every now and then, when I switch back to my Ubuntu PC, it fails to pick the sound card up and even restarting Pulseaudio does not solve the issue.

So, I created a small script in my home directory and called it restart-pulse-audio.sh with the following content:

`!/bin/sh`

systemctl --user restart pulseaudio systemctl --user restart pipewire

Just run it whenever your card is not picked up as you switched it off/on and it should get it alive and kicking.

Logarithmic penalty

Zarrelli il martedì, 9 Giugno, 2009

The reason we don't want it is that there's a logarithmic penalty for
adding things to the initramfs, because not only does it have to be
loaded from disk, but it has to be decompressed, unpacked and cleaned up
afterwards.

Ma chi vi ha detto che BitTorrent serve solo a scaricare musica, film e programmi?
Date un’occhiata a questa guida e sfruttate l’indubbia velocità del p2p per aggiornare il vostro sistema da Hardy a Ibex, senza mettere sotto sforzo i mirror di Ubuntu.
