Comment 25 for bug 1926165

The testing kernel for yoga 9i: https://people.canonical.com/~hwang4/lp1926165/v2/, install this v2 testing kernel, don't need to run the script, check if the bass spk works or not.

For c930 and c940, the testing kernel is not suitable for them, they only defines main speaker, this is different from yoga 9i, need to do more change than 9i. Let us fix the issue on 9i first, then try to fix the issue on c930 and c940.
