moode running from nvme

[dersucher]

Hello!

Does anyone running a moode installation booting from nvme?

I copied mine with rpi-clone from sdcard to a nvme. 

The debian os boots fine and moode also but every time I start the pi5 new, the previously selected audio device is not choosen, it wants to play through hdmi.

- USB-DAC is ESI Dr. DAC nano acting as SPIDIF source for another DAC
- RPI5 with moode 9.0.8 installed on 250GB nvme with pi-hat

Today I copied back to SD card, and the issue never occurred.

I think it could be something with the speedup in booting form nvme, so the usb-audio device is prolly detected to late. Where can I set some "slowing down" wait seconds ;-)


What I not forget to say: The great work of the moode team is fantastic

Thats interesting. It could be that moode startup which includes audio detection and configuration completes too fast when booting from NVMe. IME its best to keep the boot media separate from the data drive as is typical for servers. This avoids having to reload all the data if you ever want or need to start with a fresh image.

Use top quality surveillance-grade uSD cards for example WD Purple QD101

To test your "slow down" theory edit the file
/var/www/daemon/worker.php

Add the sleep(30) line just below the startup sequence comment header, save the file and then reboot.

Code:

//----------------------------------------------------------------------------//
// STARTUP SEQUENCE
//----------------------------------------------------------------------------//
sleep(30);

sysCmd('truncate ' . MOODE_LOG . ' --size 0');
$dbh = sqlConnect();
$result = sqlQuery("UPDATE cfg_system SET value='0' WHERE param='wrkready'", $dbh);
.
.

Tim, many thanks for the answer, I will try it and report the change in behavior.

Yes you are not wrong when keeping boot media and data separated but I use that installation also for paperless-ngx under docker so the documents processed on the sdcard does not sounding good for me and the life of the used card.

I will report!

The "sleep" does not affect it.

It seems that the usb sound adapter not correct recognizing by the rpi kernel usb subsystem, sometimes the string got in lsub is shortend by whatever.

I will explain:

After some reboots, the USB Device-String changes, not the Device ID which is (my example) every time 0A92:0054.

If I successfully chosen the output in snd_config.php and doing some ore somtimes one reboot or complete shutoff und poweron cycle and the USB Device name changes, alwasy the HDMI is selected, so the playback runs into error.

Then I manually select the "other recognized" card 0, the playback will work perfectly.

After some reboots, the old Device Name is back and the Output selector is missing the previously configured "string", so the playback is switched to HDMI1

I would hack it with always choosing the first card entry filled in the snd_config.php but I'm not familiar with php to do that.


When it is displayed as Dr. DAC Nano lsusb shows
Bus 003 Device 002: ID 0a92:0054 EGO SYStems, Inc. Dr. DAC nano

Whet it is displayed as 0x92:0054
The Dr. DAC nano is missing in the string.

Perhaps it is possible to hack it to select always the alsa card0?


Many Thanks for you help in advance

The weired thing is, that this did not happen, when booting from SD Card....

With another USB Sound device it is the same, also on another rpi5
