RPi4 + CamillaDSP Tutorial

[Wirrunna]

Have you tried using the latest version of the GUI?

The way to tell if you are on the latest GUI is check the VU Meters and confirm "In" and "out" are sideways as displayed on the enclosed screen grab.
As Marcos said the remote moves the volume with almost no delay.

Edit: Just noticed that Michael has updated the screen grabs of the GUI to the latest version.

Is it possible to stream via Roon under Ubuntu Server 22.10 rather than LMS, Spotify or Tidal?

 

[mdsimon2]

Sure, just install Roon Bridge -> https://help.roonlabs.com/portal/en/kb/articles/linux-install#Manual_Install. For 64 bit ARM you want to use armv8.

And of course Roon has its own DSP capability which is somewhat redundant with the approach described in this thread.

Is there any way to easily switch capture devices without having to use the CamillaDSP gui every time?

I plan to get this UR23 optical to USB adapter for connecting my PC or a TV but I also want to use Shairport for Airplay streaming.
Opening the web interface every time is not the end of the world but being able to use a flirc remote would be more convenient

Yes, this can be done with the FLIRC. I am in the process of implementing some more general switching behavior to the oled and flirc python scripts but won’t be able to finalize until the end of the month.

Is it possible to create named groups of filters within Camilla DSP? Active speakers (such as the LX521.4) employ numerous filter stages for each driver. It would be convenient to aggregate all of the required filters for the each driver into separate, appropriately-name groups so that a bank of filters could be easily applied to it's corresponding driver channel.

Edit: In retrospect, my request above seems unnecessary since all filters are stored in a named configuration along with the channel pipelines which specify the filter chains. So as Emily Litella would say - "Nevermind".

Hi i just wanted to ask: did any body manage/try to use Camilladsp with Ac3 5.1 audio from toslink or spdif ?

I am building a cheap as possible home theater setup and thought this could be a way to achieve relatively cheap room correction.

 

[juliangst]

Just tested installing shairport with Airplay 2 support but I can't get it working.

Has anyone alreadytried to get Airplay 2 running on Ubuntu?

It can be done but it is somewhat complicated and expensive, I am not sure it is worth it if cost is your primary motivation.

You need a decoder such as the Dolby DP562, fortunately these can be purchased for under $100 used, I purchased one for $65 shipped earlier this year. The decoder will take an optical AC3 5.1 signal and turn it in to 3X stereo AES outputs. From here you have two options, 1) an Okto dac8 pro where you take the AES outputs of the decoder and use the USB/AES mode to route the AES signals to CamillaDSP for processing and back to the Okto for analog output or 2) a miniDSP U-DIO8 which can route the AES signals to CamillaDSP and back out to AES outputs although you will need DACs in this case.

I have not but use normal shairport-sync all the time.

ac3 can be decoded in SW, e.g. ffmpeg, gstreamer etc. Then through aloop to CDSP with async resampling.

But the question is overall latency, for lip sync. The more stages, the more buffers, the longer the latency...

 

[juliangst]

I just made a fresh install of CamillaDSP but I can't access the web interface. It looks like the port is blocked by something.

Are you running shairport-sync? If so you need to change the port of shairport-sync to 6000 as described in the tutorial as both CamillaDSP and shaiport-sync use 5000 by default.

Already changed the port to 6000 so shairport is not the problem.

Something using python is blocking the port but the only possible python script running is CamillaDSP itself.
I did another fresh install but still got this same error

 

[phofman]

'netstat -a -p -n' will tell you which process/PID uses the port.

'ps axwww' will show you the process/PID parameters.

Using these commands should help you find out what is blocking your port. I would guess you are trying to run a second instance of the GUI.

I recently purchased a Motu M4, installed the latest version of Moode on my pi4, and have been struggling to get 4 channel playback via CamillaDSP. M4 is selected as the playback device and loopback is enabled in the audio settings. In CamillaDSP I have tried the settings suggested in the config files, but I only get just a moment of 4 channel playback before it stops. When I go back to the GUI the status says paused. When I open the log it shows "...src/alsadevice.rs:152] prepare playback after buffer underrun". When I disable CamillaDSP playback in fine. Thanks in advance!

I also had trouble when trying to use Moode's loopback. Try to follow this below starting from a generic "flat" configuration with the pertinent changes. Good luck

Thanks for the suggestion! I'll try it later today.

Thanks MarcosCh, I'm up and running! Here is a screenshot of my settings:

 

[juliangst]

Got CamillaDSP running again but I don't get any audio from Airplay.

I doesn't seem to be caused by Shairport because I see my Pi in the Airplay menu and can stream music to it. The output device of shairport is "hw:Loopback,1"
I'm using the same setting that I used on my CamillaDSP server before.

Any ideas what I'm doing wrong this time?
