1) originally we use speaker-test to test HDMI/DP/Legacy, failed on
Ubuntu 20.10. with 5.9 official kernel, works fine.
2) now we change to another method to test audio, works well.
Summary:
Seems test tools has some issue.
5.9 official kernel support speaker-test, but in 5.8 (ubuntu 20.10), doesn't
support speaker-test well.
new method to test audio:
