External usb sound card not working

Postby Ryoga_AG » Wed Nov 01, 2017 5:30 am

Hello!
I just installed mint 18.2 in dual boot with windows 10 but I have a problem with the external sound card, when i play any sound all i can hear from the headphones is a strange noise.
The card works fine on windows so it's not an hardware issue.
I searched for similar problems but the same card for other people, that uses mint or ubuntu, worked fine.
The card is the csl 7.1 external usb sound card.
I tried to adjust the card settings but nothing changed.
What can I do?

P.S. sorry for my english (I'm Italian).

Add tsched=0 to the of end /etc/pulse/default.pa.

In a terminal:

Code: Select all

sudo echo 'tsched=0' >> /etc/pulse/default.pa


Then reboot.

That might complain about permissions, in which case use this:
echo 'tsched=0'|sudo tee -a /etc/pulse/default.pa

I found something new
When i plug the external card the computer run slower, in a youtube video i would see frame by frame.
So the noises i hear are the normal sound slowed down.
Is there some performance option i can disable?

EDIT: not all the programs run slower, just everything sound related, so if i try to listen to music it will be slow down, same for video.
