Status in Ubuntu Studio Website: Invalid Bug description: After an update about a month ago audio through my Focusrite 2i2 is "chirpy" and distorted. It worked prior to whatever update came down the pike about a month ago. As I say, audio playing through my USB Focusrite Scarlet 2i2 is "Chirpy" and distorted. If I listen with earbuds out the laptop's analog output the audio sounds fine. This is out of the headphone jack on the 2i2 and out of the balanced TRS on the back. The interface works fine with every other computer in the house. Tested on 3. I am running Ubuntu Studio 20.04 LTS on a Lenovo Thinkpad laptop. Kernel version is: 5.13.0-40-lowlatency I just tested again and there seems to be a sample rate issue as well. In addition to being distorted the music seems to be slower and lower in pitch. I didn't make any changes I am aware of to ANY configs on this laptop. This just started suddenly happening after an update.
