MOTU Microbook II

[MARCO_1974]

Hi All,
I'm new user with Ubuntu 20.04.01 lts and in general with Linux. I've tried to install my Motu Microbook II, it's work properly with piano and guitar, without install any software like Cuemix or Cubase etc (since two weeks ago I've always used with windows). But it doesn't work for listen any files mp3 or youtube videos or moves....I'm trying to understand how to Linux works but it too difficult and in the same time I need to use my card Microbook to record and play Guitar.

Now I've connected my motu microbook II by usb to my laptop, my lespauls with pod hd400 and by headphone i could listen very well.
In the same time I'm watching a jazz event live by Facebook but it doesn't work. I can't listen anything and it seems like slow motion video:( Also I've tried to connect my Logitech Speaker System Z313....the same problem...
Thanks in advance for your help and to following me.

otherwise could you please give me some advise in order to buy a new audio card compatible with ubuntu 20.04.01? thanks for your help.

I guess your problems are in understanding the complexity of the different sound and MIDI systems in Linux.

I'd start in playing youtube-Videos and trying to understand the pulseaudio controls.
