Re: [SlimDevices: SqueezeCenter] LMS could not reestablish any USB connection after USB Dac is disconnected

2021-03-07 Thread sisiko


Thank you for responding!

Raspberry Pi 4:

I can do whatever I want (turn speakers or squeezelite on and off) and
the active speakers with their build in DAC will be recognized by the
Pi.
I also have a setup with it where I power the speakers on and off with
sequeezelite (see the post "'[piCorePlayer] Turn off USB output when
turning off player?'
(https://forums.slimdevices.com/showthread.php?112760-piCorePlayer-Turn-off-USB-output-when-turning-off-player)").

Raspberry Pi Zero:

The speakers are also used by my TV, so I would appreciate the Pi 4
independence of turning squeezelite or speakers randomly on and off. But
due to (maybe usb controller hardware?) technological differences
between the Pi Zero and the Pi 4 it won't work with the Zero.

The "plughw" also didn't solve it. I have this issue also under
Raspberry Pi Os with a Pi Zero: turning the speakers off and on again
will not show them with the command lsusb again. To get them visible
again I also have to reboot the Raspberry Pi OS Pi Zero.

ItÂ’s the build in DAC from these active speakers:

So basically I cannot turn them off and on again and listen with
piCorePlayer without restarting it.

I encounter the exact issue on a raspberry pi zero with picoreplayer and
an external dac. 

On a pi 4 it is not a problem. 

But on a pi zero the usb dac "output setting" options in picoreplayer
dissapear and do not reappear after dis- and reconnecting the external
DAC.

With the DAC detected my "output setting" options look like this


Code:

sysdefault
  default
  plugequal
  equal
  hw:CARD=Audio,DEV=0
  plughw:CARD=Audio,DEV=0
  sysdefault:CARD=Audio
  front:CARD=Audio,DEV=0
  surround21:CARD=Audio,DEV=0
  surround40:CARD=Audio,DEV=0
  surround41:CARD=Audio,DEV=0
  surround50:CARD=Audio,DEV=0
  surround51:CARD=Audio,DEV=0
  surround71:CARD=Audio,DEV=0
  iec958:CARD=Audio,DEV=0



and I tried "hw:CARD=Audio,DEV=0" and "front:CARD=Audio,DEV=0" without
success. 

Does anybody have another tip or hint to try?
