01-15-2023, 03:02 AM (This post was last modified: 01-15-2023, 03:06 AM by gwurb. Edit Reason: Added CamillaDSP SR and chunksize. )
There seems to be an issue with the way that CamillaDSP works on Moode. I haven't tested this outside of Moode so no idea if the issue rests purely in CamillaDSP or if its related to the way that Moode handles MPD and CamillaDSP.

The hardware is:
RP4 with USB DAC/audio interface, 4 channel output Motu M4.

CamillaDSP is setup to have:
2 channel input to 4 channel output mixer and a couple of filters. The pipeline is 2 input channels to 3 output channels with a filter on each of the 3 channels. Samplerate is 96000, chunksize is 2048 as per CamillaDSP github for samplerate of 96000.

Issue is reproduced by playing a track for about 10-15sec and then going to another track. Instead of playing the next track an error pops up. The error is 'MPD error Failed to open audio output". Pressing play straight after the error results in playback resuming.

Playing a track for less than 10sec, or longer than about 20sec does not result in the MPD error. But, there is a CamillaDSP error when playing a track for less than 10sec.

CamillaDSP logs:

Is the issue related to the way that Moode handles MPD or CamillaDSP when starting a new track?

I know very little about DSP or Camilla but from your post the 'buffer under-runs' seem to be a feature.
Have you increased the buffer in the audio set-up ? mpd-settings.

Someone more conversant than I will be along soon I expect :-)

I did increase it to 16MB. Decreasing it back to 4MB doesn't fix the problem. It changes how long I can play the track before skipping for the error to occur. Here is a CamillaDSP log example with 4MB MPD buffer and going from track to track.

The question, really, is why are buffer underruns occurring AND resulting in MPD error in Moode. When I was playing with CamillaDSP settings I noticed that at least one of them does not apply on Moode when I select Apply to DSP. It seems to apply but then if I choose Fetch from DSP then the wrong value is returned. So Moode's interface/implementation to CamillaDSP is not generic.

Reboot and post the startup log.

Code:
moodeutl -l

*Not sure why SMB does not auto mount on start up but manually mounting it via GUI is fine. It auto mounts after a while. Maybe because I am using a USB hub with ethernet adapter? But that is not the main issue.

That's a fresh reboot, and I was able to get the MPD error to occur after this reboot.


To remove USB hub as an issue I plugged everything straight into RPI4 (ethernet cable into ethernet port RPI4 and MOTU M4 into RPI4). Can still get MPD error to occur but it's harder to get it to trigger. Logs:

The moOde startup log suggests some sort of network issue. An Ethernet connected Pi should get an IP address from Router almost instantly during the Linux part of system startup and before moOde startup but the moOde startup log shows "eth0 address not assigned".

Code:
20230116 114012 worker: eth0 adapter exists
20230116 114012 worker: eth0 check for address (Off)
20230116 114012 worker: eth0 address not assigned
20230116 114012 worker: wlan0 adapter does not exist
20230116 114012 worker: apd0 router mode (Off)
20230116 114012 worker: No active network interface

You could try turning on "Wait for Ethernet" in System config and leave the timeout at 90 sec default. This will cause moOde startup to wait up to 90 seconds for an Ethernet address to be assigned but this may just mask an underlying network issue.

The lines from Camilla in the MPD log indicate no audio device detected.

Code:
Jan 16 11:43 : output: Failed to play on "ALSA Default" (alsa): snd_pcm_poll_descriptors_revents() failed: No such device
Jan 16 11:43 : exception: Failed to open audio output

No USB hub in the chain anymore...

The wait for ethernet works...

I don't know why the system suddenly decides that there is no audio device detected. Can you think of anything that Moode is doing that may be contributing?

Maybe some issue with the USB connection between Pi and audio device for example not enough power, bad cable etc.

But why would it only cause a problem on track change when the previous song has only been playing for a particular amount of time?

I might try asking on diyaudio camilladsp thread.
