TBH I was somewhat hoping some others would post some similar observations to those below before me, as I couldn’t believe I was the only one with these problems.
Having discovered that image 20200720 would no longer access the Addons page, or extract cover art from FLAC files without a needed downloaded file. I downloaded the latest image from the first post (20200721) and set about creating a new installation. As reported by others this version seemingly has problems with the MPD library. After watching the flashing library tab for 20 mins I too can confirm that once completed there were no files reported on the library icons, or found on the attached USB drive shown in the ‘Sources’ menu page.
Installed update 202008061 rescanned the library and there were the files. Although, the Albums icon now seemingly reports the total number of discs, rather that albums. If you take account of each individual disc of a double or triple album CD being in a separate folder within the main album folder (CD1, CD2… etc.).
The bigger problem – after applying update 202008061 and updating the library I found I couldn't activate my I2S S/PDIF HAT. The System page I2S switch activates and allows you to select the required HAT in the menu, but doesn’t then prompt you to reboot on leaving the System page to activate it. And a manual reboot does nothing but reset the switch to the default off position.
Anyway, four further attempts to re-image the SD card and start from scratch ended up with a few notable problems in both 20200721 and 202008061.
In 20200721 you can activate an I2S HAT, but the activation is seemingly locked once the 202008061 update is applied. If update 202008061 is applied before a HAT is first set in 20200721, you can’t activate it at all.
The Sound Profile setting doesn't work in either 20200721 or 202008061. After selecting the required profile and rebooting, the setting always reverts to the default RuneAudio profile.
The Wifi switch is missing in the System page of 202008061. Subsequently, you can’t turn off Wifi unless you do it in 20200721 before updating to 202008061.
Not sure on this one. But apparently, the GPIO option is permanently on – since I get a GPIO pop up showing each switch deactivating when powering off the system. Even though the System page reports the GPIO option is off.
This one existed in 20200720 as well: Once the browser is rebooted after first activating the mouse cursor in the ‘Browser on Rpi’ settings – the ‘Browser on Rpi’ button is shown as off and the settings gear icon disappears a few seconds after the button is reactivate. If you do manage to open the settings menu again in the few seconds the gear is visible, the numerical entries in the menu are blank and the mouse button is shown as off. The Rpi browser remains active and the mouse cursor visible regardless.
System: Rpi3B+ > Allo DigiOne Signature.
Hope some of this helps
