Additional Information (if applicable):

Software title: mpd
I bought a new allo usbridge, including allo sparky and a usbridge. Because i had trouble with the first usbridge, i get a new one and set up the system yesterday.
The whole system is "fresh", downloaded yesterday and flashed to a sd card. Currently i use sd cards, because it is quicker to exchange than the emmc card.
I added mpd and shairport-sync.
I also added Spotify-connect-web. After installing Spotify connect web the system hung. I was not able to play music via Spotify connect web. Never. When i use spotify-connect-web the systems sometimes reboot. I disabled and unmask Spotify-connect-web restart the system in order to be able to remove Spotify-connect-web.

MPD works quit well after rebooting the sparky. But sometimes it stop to work. In that case i'm not able to stream music via mpd. Typically a reboot helps. After a reboot it work at least one time correctly. Sometimes it work only one time, sometimes it work several times.

Is it more a software or a hardware problem. I try also volumio, with more ore less the same result.

One more thing.....

Because the system was not stable with DietPi. I also try volumio. There is more or less the same result. Sometimes it work especially after reboot. Sometimes it doesn't work.
What i do not understand: when it would be a hardware defect, it would not work at all.
If it would be a software defect, i wonder why i don't find more problems from other usbridge users?

[MichaIng]

@seniorgod
Many thanks for your report.

I marked for investigation. Can't do it myself due to lack of device and audio system to test.

Indeed interesting that it works first and fails to connect to the audio device (obviously). Perhaps some voltage/power drop or physical connection issue?

At least the USB get's disconnects:

kernel: usb 4-1.1: USB disconnect, device number 3
...
kernel: usb 4-1.1: New USB device found, idVendor=2772, idProduct=0221
...
kernel: [] (usb_kill_urb+0x88/0xd4) from [] (usb_hcd_flush_endpoint+0xa8/0x174)
# Followed by some more kill/disable/disconnect messages

Did you try a different cable for somehow bring the wire in a fix position, so there will be surely no motion in the USB connection?

[seniorgod]

Hm, there is surely no motion......
And as the last hifi freak under 50 years i spend 50€ for an USB Cable to connect the DAC. The same DAC with the same cable works flawlessly with my raspberry pi.
Until now i used a raspberry pi as mpd server. I connected my Project PreAmp/Dac via usb to raspberry. I wrote an u-dev rule to observe if the preamp/dac is shut on o shut off.
If the dac is shut off the dev rule stops mpd from playing.
Is the dac is shut on, i start a script via u-dev which load a playlists and start playing. That works great with raspberry pi since years. But not reliable with sparky.

What i wonder is if:
...
kernel: usb 4-1.1: USB disconnect, device number 3
...
point to the project or to usbridge from allo?
Do you think there is a physical mechanical or electrical problem?

[MichaIng]

@seniorgod

Do you think there is a physical mechanical or electrical problem?

To be true, I have no idea. It was just a guess in the blue based on the relatively quick disconnect/connect/disable logs, which is simple to verify.
Clearly not my profession, since I don't use any media system with my DietPi.

@Fourdee
Might you have a look into this?

[seniorgod]

** ok, i do some more investigations: I shut on and off my project an log the result of journalctl

the system is started
i start on my Preamp/DAC (which is always connected to sparky usbridge via USB cable)
the system find a new usb device
my u-dev rule fire and call a script which clerk the mpd playlist, load a playlist with radios stations and plays the first entry
everything is fine - i hear music

this ist the verbose output of journalctl during the above described steps

the system must rebooted to be able to connect to the DAC again

What is strange also: I use shutdown -r now for reboot. But this needs 10 Minutes.
I can logon again via ssh after 10 minutes, not earlier.

@seniorgod

Thanks for the report 👍

Appears to be a hardware specific issue, possibily system instability.

Might be worth trying the following, to see if same results:

• Different PSU
• Different USB DAC

Failing that, if problems persists, I would get in touch with Allo and reference in this ticket.

@Fourdee

thanks for replying

i investigated further.
I use the sparky together with allo usbridge which provides better "usb sound"
So i thought thats a problem can occur at that device. The usbridge is an separate board, which is connected via the 50PIN connector to the sparky.
Currently feed power by the usbridge to the sparky.
I change the connection to the DAC from the usb port of the usbridge to the usb port of the sparky. It is the same result.
I also experimented with mpc to stop playing music to the dac before i disconnect the DAC (by shutting off) .

The result is the same regardless if i use the usb port of the usbbridge or the usb port of the sparky:
If i shut off the dac while i play music to "hw:1:0" the system will see the DAC never again.
If i stop playing music before shutting off the device everything is fine. The DAC could be used after shutting on the next time.

I investigate further by changing power supply and waiting 10 minutes after shutting off..... Maybe i should also try Dietpi on Raspberry?

[seniorgod]

Dear all,

i tested different configurations today

I detached the usbridge from sparky and used a different power supply only for the sparky.
The result is the same.
When i disconnect the DAC without playing music, everything is flawless. When is shut on the DAC again, he is found by the sparky.
When i disconnect the DAC while i play music, i face the behaviour described above. The connection is broken and lost until restart of sparky.

i set up my raspberry Pi with dietpi and do the tests again
With raspberry and Dietpi all went fine.
Any ideas?
Could it be a problem of the driver for the usb hub on sparky?

One additional point.

raspberry use usb 1-1.3
sparky use usb 3/3-1
when i shut off the DAC and the problems start, the sparky always need 10 minutes to reboot with shutdown -r now.
For it "feels" like the problem is related to the usb driver, which afterwards block 10 minutes till sparky is able to reboot.
Is that possible?

@seniorgod

In dietpi-config have you tried setting usb-dac-1.1 for the soundcard? This forces USB 1.1 mode for stability.

After applying, reboot and see if it improves.

Failing the above, I suspect hardware related issue as the issue occurs on volumio also.

[seniorgod]

Hello Fourdee,

thanks for you help.
First: The change to usb-dac-1.1 only result in a quit room. I hear nothing. Maybe i can't play music because i address the DAC in MPD via "hw:1:0". I don't know.

Meanwhile the allo support send a mail. It seems there is a "trick" in the USB driver or chip or whatever else.
In the file

/DietPi/uEnv.txt

i had to change a variable from
aotg.urb_fix = 1
to
aotg.urb_fix = 0

and reboot the system.
Afterward it works.

Maybe you have to adapt that value in the image, which is offered for download?

best regards and many thanks

@seniorgod
Ah this is great. AFAIK we do not touch uEnv.txt on Sparky SBC, so yeah this is something we should do then, when selecting a USB DAC at least.

Not sure what the setting does and if there are any downsides to not apply this by default on all devices, needs some research. I reopen the topic to not forget about this.

Lol forgotten. Added to v6.22 milestone. Possibly related: #2610
I close in favour of the linked topic.
