CamillaDSP for piCorePlayer

[JWahle]

On my pcp /etc/asound.conf is owned by root:staff and the group has read/write permissions.

 

[Nikyo]

I've been wondering is there a way to enable alsa inputs for when I dont want to play through pcp? I can only select Stdin

 

[JWahle]

You should be able to:

• uninstall the piCoreCDSP extension
• reboot
• change the script line with supported_capture_types: ["Stdin"] to supported_capture_types: ["Stdin", "Alsa"]
• run the script again to reinstall piCoreCDSP

You need to make sure, that CamillaDSP is running, though:

• either have Squeezelite output to CDSP, even when playback is stopped (this should be the default setting)
• or start CDSP manually somehow

I used your script and am happily running/exploring CamillaDSP on a rpi4, many thanks. Quick question - do any of the components the script installs require a proper safe shutdown. I'm used to just powering off my pCP without ill effects as pCP/Squeezelite runs entirely in RAM (my LMS is elsewhere) and would like to know if I can continue this behaviour without risk of corruption of the sdcard.

 

[sheeple]

I do it all the time and have never experienced any issue.

 

[JWahle]

Indeed, no shutdown is required.
The only writes to the SD card are, when you save the CamillaDSP config or upload stuff via the GUI.

I have a small problem. I like to use the volume control in camilla. However it always revert back to max volume afrte sample rate change. Is there anyway I can avoid that?

[JWahle]

Currently, there is no easy way to keep the volume from before the sample rate change.
CamillaDSP 2.0 will fix that, though.
I will probably create a modified version of my script with the CamillaDSP 2.0 preview version in the coming weeks.

 

[JWahle]

If you feel adventurous, you can install the CamillaDSP 2.0-alpha5 version from https://github.com/JWahle/piCoreCDSP/tree/cdsp2.0.
I updated the script and the installation instructions.
This should fix the issue with changing volume after sample rate or format changes.
It might introduce some other issues, though

My CamillaDSP statefile broke once and I had to fix it by ssh-ing to the piCorePlayer and running:

echo '
config_path: /mnt/mmcblk0p2/tce/camilladsp/configs/Headphones.yml
mute:
- false
- false
- false
- false
- false
volume:
- 0.0
- 0.0
- 0.0
- 0.0
- 0.0
' > /mnt/mmcblk0p2/tce/camilladsp/camilladsp_statefile.yml

 

[JWahle]

I just updated the script to use the new CamillaDSP 2.0.0 with GUI.
Check it out at https://github.com/JWahle/piCoreCDSP

 

[Stretchie]

The script works perfectly as always. Thanks!
But with the new version I have the problem that the keyboard (and therefore also Flirc) no longer works. Jivelite is installed, USB recognizes the keyboard and Flirc. Any ideas?

 

[JWahle]

If you're running some python script using any of the camilladsp functionality, then it is broken, because the new version changed some names - make sure, to check the logging output.
If only Keyboard / USB functionality is involved, then I don't think this version of the script has anything to do with that.
Did it work before installing CDSP?

 

[Stretchie]

Thanks, you're right, it wasn't your script, CDSP is ok, it was my installation. I don't know what went wrong. Well, I took the easy way: old image on new sd card, CDSP old version uninstalled and V2 reinstalled. Everything works fine now.

Johannes, I am attempting an install on a running pCp9 on an RPi4b

It appears to go well until -

I have rebooted and retried 3 times.

Am I pushing it uphill trying this on pCp9 ?

I currently use CamillaDSP installed on an RPi5 running Ubuntu 23.10 driving a Motu ULMk5
(https://www.audiosciencereview.com/forum/index.php?threads/rpi4-camilladsp-tutorial.29656/).

 

[Wirrunna]

OK, I just installed on a running pCp8 on an RPi4b and everything worked.

Thank you, I will experiment further with the aim of replicating the functionality of my system as described in my previous post.

 

[capslock]

Excuse my ignorance: with PiCore, am I limited to squeezebox streaming? Or can I reconfigure the USB sound box (e.g. Motu UL mk5) to accept digital in?

 

[JWahle]

@Wirrunna for pCP 9, you have to use the pCP 9 branch of my project.

@capslock in the CamillaDSP GUI you can change the input from Stdin to Alsa. Then you can play any input of your audio interface. If I remember correctly, the Motu UltraLite only accepts 8 (all analog) or 20 input channels. You'll have to use 20, if you want to use the digital inputs.

 

[capslock]

Thanks. A digital stereo pair is quite enough.

 

[maravedis]

I'm new to piCorePlayer, but have used CamillaDsp standalone before. Can someone explain how they talk to each other?

The script worked flawlessly but I'm not getting any audio into camillaDsp at the moment. What should I have in 'Squeezelite settings - Audio output settings'?
I have camilladsp set in 'Change squeezelite settings'

I'm thinking of using this as 'headless' stand-alone multichannel-dsp with a MOTU M5 - taking advantage of the automatic sample rate changes, and using toslink input only.

Thanks!
