I am running Ubuntu 22.04 Mate. I use gupnp-av-cp from gupnp-tools package. It controls smart tvs via LAN. It works OK on Ubuntu 20.04 and earlier versions.

It detects Sony Bravia on LAN but fails to set volume, etc. via gupnp-av-cp gui.

I found the following warning in ~/.xsession-errors:

 ** (gupnp-av-cp:390810): WARNING **: 19:58:41.447: Failed to get sink protocol info from media renderer 'uuid:00000000-0000-1010-8000-F0BF97C2CB09':Forbidden

I noticed that gupnp-av-cp process opens sh then pxgsettings process.

Security Context  unconfined
Command Line  /fusr/lib/x86_64-linux-gnu/libproxy/0.4.17/pxgsettings org.gnome.system.proxy org.gnome.system.proxy.http org.gnome.system.proxy-https org.gnome.system.proxy.ftp org.gnome.system.proxy.socks

Waiting Channel  do_poll.constprop.0
ControlGroup  /fuserslice/user-1000.slice/session-c3.scope ()

What might be the problem?

EDIT:

I filed a bug report on launchpad : https://bugs.launchpad.net/ubuntu/+source/gupnp-tools/+bug/1993641

EDIT2:

Problem seems to be with system wide.

I used to play videos with chrome app vget cast but it also fails to play videos.

Another python app nanodlna which sends video to play in smart tv also fails

EDIT3:

But sending soap line manually with curl works:

curl -X POST -d '<?xml version="1.0" encoding="utf-8"?><s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><s:Body><u:X_SendIRCC xmlns:u="urn:schemas-sony-com:service:IRCC:1"><IRCCCode>AAAAAQAAAAEAAAATAw==</IRCCCode></u:X_SendIRCC></s:Body></s:Envelope>' http://192.168.1.101/IRCC#volume-down

You have confirmed with the maker of the app that 22.04 mate is supported?

@David I installed it from official Ubuntu repositories. It should be supported by the maintainer.

Yes I suggested you ask them.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
