DuckDuckGo and Google search Linux share Bluetooth via SSH and Linux Bluetooth over SSH first page of results only seem to be about SSH over Bluetooth.

The Super User answer 997814 is mostly stating that in theory it is a non-sense.

it feels like it would play the audio on another computer while the aim is to play on another Bluetooth speaker not being a computer.

Maybe an alternative is to transmit with Internet the audio output of one computer as the output on another one having Bluetooth and share such audio to a Bluetooth speaker.

At least from Debian 12 GNOME laptop to Debian 12 OverClock3000 Virtual Machine Manager virtual machine running on Debian 12 GNOME Pegasus with Remmina > Advanced > Audio output mode > Local instead of Off does not help playing the remote audio locally. Local Sound GNOME settings do not seem to show anything going on with remote VLC audio running even if restart the latter.

Well it works from my Linux Mint 22.1 Cinnamon Framework 13 to Pegasus but both with Quality Best (slowest) and Poor (fastest) the sound is jerky.

Forwarding Bluetooth Audio (A2DP)

may help.

Unclear how USB/IP for Bluetooth Dongles would be detected as do not specify hostname or IP.

btvirt and bluez could be investigated.

man ssh
Output excerpt: 
       -R [bind_address:]port:host:hostport
       -R [bind_address:]port:local_socket
       -R remote_socket:host:hostport
       -R remote_socket:local_socket
       -R [bind_address:]port
               Specifies that connections to the given TCP port or Unix socket
               on  the  remote  (server) host are to be forwarded to the local
               side.

               This works by allocating a socket to listen  to  either  a  TCP
               port  or  to a Unix socket on the remote side.  Whenever a con‐
               nection is made to this port or Unix socket, the connection  is
               forwarded  over  the  secure  channel, and a connection is made
               from the local machine to either an explicit destination speci‐
               fied by host port hostport, or local_socket, or, if no explicit
               destination was specified, ssh will act as a  SOCKS  4/5  proxy
               and  forward  connections  to the destinations requested by the
               remote SOCKS client.

               Port forwardings can also be  specified  in  the  configuration
               file.   Privileged  ports can be forwarded only when logging in
               as root on the remote machine.  IPv6 addresses can be specified
               by enclosing the address in square brackets.

               By default, TCP listening sockets on the server will  be  bound
               to  the  loopback  interface  only.   This may be overridden by
               specifying a bind_address.  An empty bind_address, or  the  ad‐
               dress  ‘*’,  indicates  that the remote socket should listen on
               all interfaces.  Specifying a  remote  bind_address  will  only
               succeed  if  the  server's  GatewayPorts option is enabled (see
               sshd_config(5)).

               If the port argument is ‘0’, the listen port  will  be  dynami‐
               cally allocated on the server and reported to the client at run
               time.   When  used together with -O forward, the allocated port
               will be printed to the standard output.
