It looks like www-client/google-chrome just added wayland and jack
audio to the dependancies. So now I have to have Pulse _and_ Jack?

Is that truly a Chrome requirement, like the company Google wrote
the ebuild, or is this something a Gentoo dev did for some reason?

Google doesn't provide an ebuild. The ebuild is written maintained by
the kind volunteers of the Chromium in Gentoo Project. For the binary distribution from Google, those devs have no control over what
libraries the Chrome executables are built to use. All they can do is
try to figure out which libraries Chrome needs, and reflect that in
the ebuild so that after the binary from Google gets installed, it
works.

That said, there was no jack audio requirement for Chrome. I misread
the emerge output. The two new requirements that google-chrome was
pulling in were

dev-libs/wayland
dev-util/wayland-scanner

You don't have to be running Wayland, but you now need the above
wayland pieces.

There isn't actually a pulse audio requirement in the google-chrome
ebuild either, but if I don't have pulse installed, some audio stuff
in Chrome doesn't work. In web apps like Google Voice

* I can select my headset mic as audio in, but it won't work.

* I can't select headset as audio out.

Installing pulse audio fixed those problems.

I'm curious as the USB disconnect problem seems somehow to be
related to using Chrome on the host machine for sites that do a lot
of audio, like YouTube. A clean boot of the host machine, followed
by a clean boot of the VM and I've run for at least an hour with no disconnection problems. I can use Chrome for email, messaging and
reading newspapers with no problem, but I run YouTube and twice I've
had USB problems in the VM.

Yep, it sounds like doing audio via Chrome is disrupting the the USB
audio device that's in-use by the VM. Are there Linux audio drivers
for that hardware that you could uninstall to keep Chrome from seeing
it?

Yep. I didn't used to have the chrome binary package installed, but
there are a couple things that I've never gotten to work in Chromium
(e.g. Webex).

With chromium-bin, there is a wayland USE flag, but nothing for
jack.

I looked into that more, and I had misread the emerge output. It
wasn't google-chrome that depended on jack, and now I can't figure out
why it was installed. I did

# emerge -C virtual/jack media-sound/jack-audio-connection-kit
# emerge -auvND world

It didn't get reinstalled. And then a subsequenct

# emerge --depclean --ask

removed another half-dozen audio-related packagets (zita-* and
realtime-*, whatever they are). I'm sure the next time I try to use
audio on that machine it won't work.

I used to think that someday Linux sound support would get
straightened out, but it just keeps getting worse...

There is no support in Linux for this hardware. From the computer's
POV it's just an external USB device, partially an audio device, and
partially just controlled over USB. I've told pulseaudio and KDE in
general not to use it but I continue to see problems. I have no idea
what functionality the USB control port is providing.

I think the next step is to actually blacklist the device by its
USB device ID ala something like this:

https://www.projectgus.com/2014/09/blacklisting-a-single-usb-device-from-linux/

and see what happens.

This whole thing isn't overly critical to me. The device itself is
stand alone in operation. It's only attached to a computer to do editing
which actually can be done on the device's GUI without a computer, or
I can hook it to a Windows laptop, or even this machine if booted into
Windows. I was just wanting to be in Linux but open a VM to allow
me to edit more easily, which I actually can do but I have to hit the
reconnect button in software or pull the USB cable, both of which
work but are hacks.
