Hello.

I had understood that the only things that Linux Mint used from their 
own repository, were the Firefox package and Linux Mint GUI stuff, and, 
possibly, "flatpack" stuff.

The reason that I posted the query to this list, is that the text 
displayed at the URL for the change that I cited, corresponds to the 
changelog displayed from synaptic, from the particular installation, 
showing that the package change applies to the Ubuntu package, from the 
repository for Ubuntu 22.04, and, the changelog for nthe package, shows 
it to explicitly be a Ubuntu matter, with the person who made the 
package update, being at canonical.com.

As this mailing list does not allow screenshots to be posted, due in 
part, to the 40kB message size limit, I can send to you, off-list, the 
applicable screenshots, if you want, to show that the particular 
pulse-audio change is from the Ubuntu 22.04 repository, rather than from 
the Linux Mint repository.

However, and, I had not posted this to the list, due to the lack of 
response to my query, before the above message, but, during the course 
of last night, I watched a couple of online youtube videos, and, a 
downloaded video, using Celluloid, to find whether the problem still 
existed, and, the problem with the loss of the sound channel, appears to 
have disappeared, indicating to me, that the problem appeared to be "a 
temporary glitch" with the software update, and, the system appears to 
have self-healed.

I would not have posted the query to the list, if I had not conclusively 
believed that the problem came from an update from within the Ubuntu 
22.04 repository, making it a Ubuntu problem, which is, in part, also 
why I asked, in my initial post about the problem, whether anyone else 
had also experienced the problem, consequential to the update. If anyone 
else had responded, with a statement indicating whether they had 
experienced the same problem, with either/both of Linux Mint 21.3 or 
Ubuntu 22.04, that could have been helpful; especially, if experienced 
with one but not the other, of the two operating systems.

I am aware that this list is for Ubuntu problems, and, not for problems 
specific to Linux Mint, but, given that Linux Mint uses Ubuntu Linux as 
its underlying operating system (except for LMDE), I believe that a 
problem that arises from the Ubuntu underlying system, is approproate to 
be queried on this list.

Of course, if Linux Mint provided and supported an official support 
mailing list, or, that a sufficiently populated and active, Linux Mint 
users mailing list would be used by Linux Mint users (especially, 
including Linux Mint users more knowledgeable than me), then, that would 
be an appropriate first point of contact for such problems, but, in the 
absence of either of those, and, emphatically, given that the issue came 
from a Ubuntu repository, then, the next best option, is this list, to 
deal with Ubuntu-originating problems. Well, to me, that seems logical, 
anyway.
