no sound Ubuntu 18.04 sound card no recognized [AMD/ATI] RV670/680 HDMI Audio

Please follow https://help.ubuntu.com/community/SoundTroubleshootingProcedure

Many thanks for your response. As i worked on the trouble I also lost my
network connections as well. I tried a fresh install formatted with btrfs
then a fresh install on Ext4 resulting in no sound or network. Then I
remembered something from the manual for ASUS P5Q motherboard if the cables
for the boot drive are not in socket 1 or 2 troubles occur. When i checked
I had arranged the cables for the drives backwards plugged in 6 to 1
instead of 1 to 6. I have been working with 4 drives to make a btrfs
raid10. This morning with out any other changes than the cable order every
thing is working fine. I am very happy. thanks for your interest and
writting to me.
