Hardware fix for software problem on Rockpro64 IT WORKS!!!! I  have sound coming from My Rockpro64 usb A 2.0(my family says)

Patrice I have the same problem as do many other about the audio Jack.  Though I dont use OpenWrt( note:not sure what it is), For me its not a big issue (Im deaf), but I like to use the computer so family can use it for Multimedia.  So The family was complaining no sound. which i couldnt care since I cant hear.  Well just off of a whim, I used to be an AirForce Tech, learned how to bypass and rewire things so troubleshooting problems like that and not of software are kind of a thing I enjoy.  

I have a couple old Telescopes I use to stargaze and they need a 16bit interface so I need serial support on Meade and Takahashi scopes.
Ok the docking station I had with an old HP I used for this.  I simply plugged my USB A from the HP docking station into the USB A 2.0 on the Rockpro64 board, and plugged the speaker din plug into the headphone jack on the HP docking station and yes it works, the Family were Like yeah good dad it works great.  Oh and a bunch of stuff shows up in the audio streams of your audio controls - check it out.

Thats it. Hp part number HSTNN-S01X.  Its a usb docking station for audio video(serial) and 4 usb port as well as an internet plug for Hardwire.  Im sure other dockers work too!  but I havent tested them.  Dont buy the HSTNN-S02X - no audio jack there
