EMBY Theatre on Ubuntu 24.04.1 LTS not working

[MartinCheetham 5]

I 've just upgraded my Ubuntu box running EMBY Theatre (3.0.21) to 24.04.1 LTS (noble).  EMBY Theatre now won't play videos or music; just get the spinning wheel.  The EMBY web interface works fine so my EMBY server is OK.   I tried a reinstallation of EMBY theater and got the following messages; librasound2 is a virtual package provided by: liboss4-salsa-asound2 4.2-build2020-lubuntu3, librasound2t64 1.2.11-lbuild2 (= 1.2.11-lbuild2),  You should explicitly select one to install.  e:Package 'libasound2' has no installation candidate.  I don't know if this is causing the problem but something is not right.  Can you comment or can I provide more information as I am clueless as to what these messages mean.  Thanks.

This might be relevant;

but when I tried to install librasound2t64 it was already installed and at the latest version (1.2.11-lbuild2)

I'm happy to help but I don't know anything about a compositor.  I could install EMBY theatre on windows, ubuntu, QTS, iPhone, ipad & a Sony smart TV.

Incidentally I've installed the snap version (3.0.21) of Emby theater on unbutu 24.041 and it works OK but I suspect that the replay volume if reduced.  This might be an issue with putting 5.1 sound through a stereo amp.  I need to check more.
