I've got an other sound issue with 19.10 on desktop with PCIe sound card.
Kdenlive plays sound on my HDMI monitor instead of my PCIe card since 19.10 dist-upgrade, and I found no way to change this (this is also default with VLC, but easy to change with Audio Menu).
No error logged in my /var/log/syslog

Hi

I have upgraded to Ubuntu Studio 19.10, and now there is no sound. I am using the Whisker menu, since that is the only menu bar I could find that even had a volume control on it. If I click on the speaker icon there, and then “Sound Settings …”, nothing happens.

In fact, something does happen. According to /var/log/syslog, indicator-sound-service appears to crash. Here are the relevant lines from syslog:

Nov 24 06:45:08 rivendell indicator-sound-service[2616]: **

Nov 24 06:45:08 rivendell indicator-sound-service[2616]: ERROR:../shell/cc-shell-model.c:458:cc_shell_model_set_panel_visibility: assertion failed: (valid)

Nov 24 06:45:08 rivendell indicator-sound-service[2616]: Bail out! ERROR:../shell/cc-shell-model.c:458:cc_shell_model_set_panel_visibility: assertion failed: (valid)

I am looking for suggestions on how to fix this. If anyone has further questions, I will try to answer, but I am not sure what is going on. Unlike what I read from Mac below, UBS has always worked for me out of the box, without needing to touch Ubuntu Studio Controls. Looking at it, I notice things like “Jack Master Device (no USB)” set to “Default”. I would like to know what it thinks the default is, but that is all it says.

hmm...just another data point, I have been running 19.10 on two PCs for several weeks.

I have had no crashing issues. And, I routinely stream from Youtube at the same time as playing local audio.

The UB Studio controls let me set up jack to run all the time with a pulse audio source/sink that get all the system audio. UBS Controlss just sets it up and it it's there evey time I boot.

I like Carla and have not even looked at QJackctl for months.

I had some trouble with firewire. I have not had more time to fiddle with that.

Mac

    Hello All,

    I upgraded to 19.10 as I wanted to find a distribution that would
    finally allow me to play audio regardless of whether it was
    streaming via Youtube or Spotify or from my DAW or any place I
    care to run it. So I upgraded as I was sick of the Pulseaudio vs
    Jackd battle. Still I seem to have the choice of one or the other
    (but not both) and then I have to stop or start jack and all the
    pain that this brings.

    On top of this the menu system randomly removes whole categories
    without any user intervention. Then there are the constant crashes
    where bizarrely the audio carries on playing after the rest of the
    system is dead.

    I tried the Gnome desktop thing with Wayland but there the
    screensaver doesn't work and there are no menus meaning you have
    to memorize the names of any programs you may want to run and
    search for them.

    I do appreciate that this is open source and I know people put in
    huge amounts of time. But with each release I guess I kind of hope
    this finally will be where Linux really gets to show how good it is.

    I am now looking at doing a complete fresh install of an OS but
    not yet decided on which flavor or even if it should be Linux. The
    jack vs Pulseaudio in my opinion is a massive design flaw and as
    long as that remains this will never be accepted as a serious
    music platform which is a shame.

    Sorry for the rant - I really wanted to be able to use this but I
    guess it's not ready yet.
