Facel

I don't understand how simply replacing the power supply with a linear power supply improves the audio quality which, in the case of the shield, suffers an inherent degradation in Android.

thank you

Could you provide a complete list of OS running on USBridge signature (ex: DietPi, Moode, RaspberryPI OS 32 Bits, ... etc ? regards

Does Moode 6.4.0 is using kernel 4.14 ? (in case of a no answer what should you do in order to have kernel 4.14 ?)

I have made further investigations and installed Volumio and Moode Audio for testing DLNA Mode The issues is with High rez (>96 Khz) files Flac playing through DLNA on a USBridge Signature. The music stops and starts again , as if there ware not enough flow rate on my gigabyte network .. 1) Volumio (DLNA mode) = Plays flawlessly all Flac Files (*) 2) moOde Audio (DLNA Mode) = same problem as DietPi with High rez flac (*) There is no problem for playing files, but there is an other slight audio problem. When playing I can here from now and then some "little audio scratches" as if I was listenning to a Vinyl! I did test with and without linking Shanti Ground to USBridge Sig Ground but it does change anything.

Playing Issue with DieptPi on USBridgeSig.. The DietPi version can't play correctly Flac Files hosted on an Intel Nuc running Jriver as Media server. The USBridge is connected to my DAC (Amanero 384 driver) and used as DLNA renderer with GMRender. The problem is still there after installing JRiver on DietPI and playing through JRiver instead of GMRender. When I switch to volumio on The USBridgeSig its plays flawlessly Is allo aware about this problem .??...

@Allo ... I am quite surprised to be the only one with this problem ...and also by your PM .. unless nobody care about upgrading dietpi OS. When I use the allo web gui image (https://dietpi.com/downloads/images/DietPi_RPi-ARMv7-Stretch_AlloGUI.7z) I can access the allo web page, The Allo image is based on dietpi V6.14 (sept 2018) .. last version is V 6.26... As soon as I upgrade the dietpi version ...the allo web page is faulty. That is probably due to a compatibility problem with PHP as PHP upgraded prompt a warning message , and is embedded into the dieppi upgrade. =>Thanks to Allo for providing a solution for this case. In addition I also have problem when playing 24/96 files with the signature is DLNA mode (GM Renderer) ... I need to investigate but I do not have such problem with the "basic" USBbrige ...

I have just received My USBridge Signature ... When I try co connect to allo web page I only get acces to a Page without any command on it (there is written dashboard but it is only text (not a link to another web page) !!!

Thank you very much Mitch for your detailled answer. Could you disclosel which DSP software will be reviewed in AS and when wil you plublish it ?

@mitchco Have you released a new edition of your book "Accurate Sound Reproduction Using DSP" ? thanks

My backup question : How do you proceed to backup The eMMc card of a SPARKY board from a windows PC ? (I am asking because you have 2 partitions, and Win32 Disk imager can only managed one partition ) thanks for your help

To reflash the SD card is not a good solution ..and i do not see the link with the fact that dietpi.local is not reachable (which is to me rather related to a dns resolution problem as the gui web page is reachable through its IP address)

I cannot access the web page with dietpi.local !!

@kotlarix => Yes

I have been using the USBridge for monthes . I cannot login anymore via the Allo GUI Webpage. I can acces to the web page http://X.X.X.X/allo/public/index.php/login , but a soon as the user and passwd are entered I have the following error How could I get it back in order ? (Without a complete re-installation) ? Thanks for your help I am running Dietpi V6.22.3 Whoops, looks like something went wrong (2/2) QueryException SQLSTATE[HY000] [1045] Access denied for user 'allo_db'@'localhost' (using password: YES)
