evdi VS catt

git clone https://github.com/DisplayLink/evdi.git

So I'm currently on Ubuntu 22.10 with Mesa and asahi-edge kernel. You need both to allow using primary GPU as source output. I'm using evdi 1.13.1 with the correction to set the module to the 1.12.0 to run the script displaylink from Synaptics for Ubuntu.

The RPM version never worked for me. It's only useful for getting the services installed. After that clone the repo from https://github.com/DisplayLink/evdi and change to the devel branch. Run make and sudo make install. If you use SecureBoot you also need to sign the resulting evdi.ko with your key. After that restart displaylink.service or reboot and it should work. At least it did for me. I's been a while since I had to use it.

I'm afraid this might be a hardware issue, maybe with the cable. I don't have a second cable to swap out unfortunately. A new one won't be here until Saturday. And it seems like a hell of a coincidence for the cable to fail when there's other issues reported within the last few days that seem very similar.

Theres a bug in the 6.2 kernel right now with at least the evdi package (dont know about evdi-git) but can be fixed with a patch. Pr for it is already open but yet to be merged https://github.com/DisplayLink/evdi/pull/401

You might want to look into catt for Chromecast:

- https://github.com/skorokithakis/catt/

But I'm not aware of what the equivalent would be for Amazon-type casting

I wrote a wrapper around catt for playing music to my house speaker-groups. It also works with video but I don't use that as often so it might be buggy--better to use catt directly

- https://github.com/chapmanjacobd/library

There might be other apps that effectively do the above, perhaps even streaming the file so you only need to wait for the first part of a file to transcode before it starts playing. I don't use Amazon devices but with Chromecast you can use catt, VLC, and possibly ffmpeg to do this. For example, you can use catt scan to find the IP address and then do vlc --sout '#chromecast' --sout-chromecast-ip=$ip --demux-filter=demux_chromecast --sub-file=my.srt my.mp4. Maybe something similar exists for Amazon.

> "Whatever app I use to play music needs to support chromecast audio."

If you can't find something pre-built that fits your specific needs, you could perhaps "quick and dirty" script yourself up something using "Cast All The Things" [catt@github][0] to talk to your ChromeCast devices, and maybe "Beets" [beets@readthdocs][1] to manage play / playlist commands and management of the music library itself, presuming some Python scripting skills on your part, or a willingness / interest in learning said skills.

CATT (which I wrote) does the same, except it supports whatever site youtube-dl supports (which is basically everything):

I have used catt to control a Chromecast. If Kodi can be made to act like a Chromecast it would work, perhaps there's a plugin for that.

Have you tried https://github.com/skorokithakis/catt ? You can ssh to your pi and cast from the command line, give it a shot!
