Comment 6 for bug 1874698

Okay. I will use "dsp_driver=1" for now then. Just for your information, before I installed Ubuntu 20.04, I used 18.04. On 18.04, I tried a few kernels on https://kernel.ubuntu.com/~kernel-ppa/mainline/ ranging from 5.3.x, 5.4.x, 5.5.x, 5.6.6 (I can't remember which x I tried anymore). I got the same observation I reported here for both cases (with dsp_driver=1 or without).
