No audio on HDMI after u-boot upgrade
#1
Hello all,

A couple of months ago I flashed the spi from my RockPro64. It worked and I was able to boot from USB3. Tried it a couple of times just to see how it worked but kept booting from the sd card (I've been using LibreELEC, btw).

The thing is yesterday I got a case to a ssd I had here, connected it to the USB3 and tried to boot. It didn't work. I imagined that it could be due to some lack of support from the relatively old u-boot I had flashed before, so I downloaded the newest version from here. I followed the instructions from here and things at first seemed to have worked fine.

Now the issues:

- First thing I noticed (and that had me thinking the flash proccess worked) is that now I have a verbose boot that I didn't have before. The ssd still doesn't boot from the USB3 port but I noticed it boots from the USB2 (maybe it was already booting from USB2 with the old u-boot, but I didn't do this test before reflashing). When connected to USB 3 it shows a lot of debug messages, but doesn't boot.

- If instead I use an USB flash drive it boots ok (both from USB2 and 3), which makes me think that it's maybe some compatibility issue with my case/adaptor, although it works fine with USB2.

- But the worst part is the audio... After upgrading there's no audio from HDMI, no matter if I boot a LibreELEC img from the sd card or USB2/3. I even tried to erase the spi using the img "erase_spi.img", but it didn't work (at least I think it didn't, because I still can boot from USB and the debug messages still show up).

- I also noticed that if I boot from another img I had here (this time a 'complete' Linux - Manjaro, not LibreELEC) audio works.

I'm attaching the logs I see when booting from the sd card after upgrading u-boot (no HDMI audio):

Is there anything I can do to at least fix the audio? Since I use this RP64 mostly to consume media (LibreELEC) it's essential.

I appreciate any help from someone more experienced.
