| USB3 enough to power 2,5 external HDD? |

Hey guys, is the Rock64 able to supply enough energy to one of those small external HDD?
I was using an external HDD with its own power supply, but decided to go with one of those small HDDs, but I think the board is not delivering enough energy.
I tried an USB 3 (500Gb WD My Passport WDBKXH, WDBY8L) and an USB2 HDD (an old Samsung 1TB External M2 Portable).
According to some info, the first needs up to 650mA and the second needs up to 850mA.
I tried each in the corresponding USB ports. Both are detected by lsusb command.
Lsblk also shows both the drives (I'm not connecting them at the same time).
However, a few seconds into the actual process of write and read, they both "disarm", as if they suddenly lost power, and then reconnect.
dmesg logs a lot of errors:

Both HDs are good and working normally on my Windows PC, so it's not hardware fault.
I'm running the latest Armbian Strech and I use a 5V 3A Power Supply. My Rock64 is slightly underclocked to top at 1008Mhz (so I don't need a fan).
I've seem many people saying that these boards in general don't supply enough power to these small external HDDs.
However, people say that the Rock64 can deliver up to 950mA to the USB 3, so in theory this should be more than enough to power at least the WD USB3 drive I mentioned above.
What do you guys say? Should I try another system image? Has anyone got a working setup involving smaller external USB3 HDDs like the ones I mentioned?
EDIT: It was the power supply. I bought a better one and now it's handling the HDD properly.

Hi everyone.
I received my Pinebook 64 last week. I installed the default Neon OS.
I cannot get the sound to work, the volume shows as 100% but nothing out of the onboard speakers or headphones. I can’t find anything in the settings.
Anyone got any advice?
Thanks, Andrew

As you can tell, the new forum is up; you can read about it and the functionality here.
To the best of our knowledge the update went smoothly and everything works.
If you experience any issues or find something broken, please report it here. Thanks!
[edit] due to feedback we've gotten we'll be trying implementing a couple improvements in the next few days - the forum will stay up, but you can expect to experience broken icons etc.,

| issue with kodi freezing randomly |
|

HI there,
I have the NAS case with the RP64. I installed the latest MrFixit image on it and managed to install/setup:
- samba (to have a network drive)
- Rsync (to backup the network drive)
- remove pulseaudio to avoid random freeze as it's currently an unresolved issue)
- install Kodi to have a media center (to read the video / music / photos I save on the HDD)
the issue is with Kodi as when I run it I get random freeze (where nothing is working anymore (no ssh, no network access, image on screen is frozen). The freeze has the same behavior as the issue caused by pulseaudio.
Would anyone have a working kodi (other than the specific distro available)?
What has kodi in common with pulse audio? this issue might be linked with the pulse audio issue somehow and I would like to resolve it if possible.
Thanks for anyone reading / helping!
