I upgraded to Ubuntu 20.10 recently and the first thing I noticed after rebooting my computer was that my application menu got flooded with many applications, all of them referring to some terms used in audio(like this) and when I open them I get some sort of audio console with their window titles in German language and the active window name on the top left being lsp-plugins
Following are the kind of windows I get when I open these apps: one when I tried booting from the old kernel(5.4.0-52--generic) and another app of the same sort when I'm on the newer kernel(5.8.0-25-generic).
I tried:
sudo apt install --reinstall lsp-plugins
sudo apt remove lsp-plugins ; sudo apt autoremove ; sudo apt install lsp-plugins
and nothing changed on the app menu, these apps even started fine with no errors even after I did sudo apt remove lsp-plugins ; sudo apt autoremove
.
When the apps are opened through the terminal using lsp-plugins-nameofprogram
the output is as follows
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
[WRN] Could not connect to JACK (status=0x00000011)
this seems to indicate there's no audio jack connected to my laptop, but I only use a Bluetooth device and I've never plugged an audio jack into my Laptop. Judging from the autocomplete feature in the terminal there seems to be 118 apps of this sort.
