Audio issues in 18.04 - distorted sound and choppy video when selecting USB audio interface - Focusrite...












0














Just getting around to updating an old Ubuntu machine. After the update to 18.04, my Focusrite Saffire 6 USB no longer works. With some tinkering in Pulseaudio and Alsa I have managed to get the device to populate in the Sound>Output Menu though it is listed as "Analog Surround 4.0 Output" even though it is a stereo setup.



This interface has worked for me in the past with Ubuntu 16.04 though even then it took some tweaking. I am noticing that when I select the USB audio interface via the sound devices tab, my video is also extremely choppy (as if it is moving frame by frame).This happens at the same time as the distorted audio. When I select the built in output, the video resumes as normal.

Things I've tried:



Removing and Reinstalling Pulseaudio and Alsa-Utils - also tried just using alsa



Changing Sound profile settings for Pulse - tried changing from 4ch surround to 2ch stereo. I got a little feedback with the pacmd list-cards output changing but nothing audible



I have tried using pavucontrol and alsa mixer but can only select the device in pavucontrol without any control over it.



Installing Ubuntu Studio Packages - no changes



edit: I have also tried creating a .asoundrc file, and editing the .conf with the following code found from here but all it did was make pulse daemon fail to start. I'm thinking this page may be of use but I cannot fully grasp what to do with the information at hand.



Does anyone know where the issue lies? Pulseaudio sound profile or Alsa driver is what I'm thinking.



Will I need to create my own driver for this? If so any help? Eventually I will probably invest in something that is more updated to work out of the box but I would love to listen to some jams while I study some python!



Thanks in advance, please let me know if I can provide you with any more information. Happy Holidays!
