[WHL] HDA - huge distortion during playback and capture

[emilchudzik]

After debugging previous issues (https://hsdes.intel.com/appstore/article/#/1506769462 and thesofproject/sof#433) where #172 was applied to repo linux-sof-dev:5300a52

• capture - silence was recorded
• playback - clear sound on jack output

After last debug kernel and topology (uploaded by Rander to my machine in 19 August) - I don't know which branch was created from (both linux and soft repo) I hear very distorded sound on jack output. Capture is also very noisy.

• checked 16/24/48kHz - 16/16, 24/32 and 32/32, 1/2/4/8 channels.

The PR to fix capture issue has been closed, so I am creating a new one

The noisy is caused by Host DMA according to Janusz

[mengdonglin]

@RanderWang Has Janusz confirmed this is a firmware issue on Host DMA? If yes, we need to move this issue to sof repo.

@mengdonglin probably it's FW issue that should be fixed when this PR will be merged: thesofproject/sof#504

[mengdonglin]

@echudzi Would you please check if this issue can still be reproduced?

[mengdonglin]

Close this issue since it's a duplicate of the known metallic noise issue of playback, and fixed by thesofproject/sof#504.
