I use Jack and I use Firefox with Jack. It works (mostly) without any problems.
Only when you have really a lot sound related tabs (maybe more than 6 active 
sound sources or so, Firefox makes new jack channels per tab), Firefox slows 
down a little bit.

I also very much recommend to use media-sound/cadence together with jack. There 
is also a version compatible with ladish (a jack session manager) in the 
audio-overlay [1].

media-sound/jack-rack for example provides certain equalizers.

Best,

I was even thinking if I could disable things like Kmix and such to make
it simple.  I remember years ago when everything was muted by default. 
After a fresh install, you would have to go to each audio program and
unmute in order to get sound.  Miss even one, no sound.  Having just one
seems to be more simple. 

Waiting on some downloads to finish before I can do anything.  May have
to logout and back in again anyway,  That silly sddm thingy is still
hoggin up a lot of memory.  I have to reset about every day to clear
that up.  Where's my hammer??  :/

I stand corrected then.  I wasn't able to get FF audio working without 
the pulseaudio use flag, but that may have been because I was trying to 
do so while still having pulse installed, or I was just "doing it wrong" 
with alsa, or something like that.  It was a couple of years ago and my 
memory isn't great, but I'm glad that there is a way to get it done.

Kmix displays both in different tabs.  Of course it makes sense to use a tool 
you decided to install (e.g. pulseaudio) rather than trying to fight against 
it with alsamixer over control of the audio.

Hi Mark,

in the meanwhile I installed quite a few pulse-related applications
and pulseaudio itsself includeing pusleeffects.

For the first, the equaliser problem is kinda solved -- I haven't
checked, whether the settings will survive a reboot.

I don't know of the quality of the sound processing of the
equaliser...but it is definetlu a step in the right direction.

Hopefully all related applications I use will cooperate... ;)

Thanks to all of us who helped! -- very appreciated!

Cheers!

That makes some sense.  I did a pretend with the USE flag enabled on the
command line just to see what all it would re-emerge and pull in as
deps.  The package you mentioned is pulled in so that should had some
function.


[ebuild  N ] media-sound/pavucontrol-qt-0.14.1


I notice KDE pulls in a new package or two as well that are some sort of
control functions.  Of course, it rebuilds several packages with the
flag change as well. 

I may give that a try.  When I first heard of it, it was pretty buggy
since it was fairly new.  It seems that those bugs were stomped on and
from more recent info, it is pretty stable and works well. 

Thanks for the info.  Helps me to decide whether to dive in or to stay
out of the water.  lol

I use FF-68.7.0-r1 with USE="-pulseaudio" and it works fine producing sound.

There's this equaliser for alsa, but I haven't used it myself:

$ eix -l alsaequal
* media-plugins/alsaequal
 Available versions:  
   ~0.7.1   [ABI_MIPS="n32 n64 o32" ABI_RISCV="lp64 lp64d"

Long answer - I don't know how much pulseaudio will remember settings from
session to session. If you emerge pavucontrol (kubuntu installs it by
default, it appears Gentoo requires you to add it. On my system it's
pavucontrol-qt) you should see something akin to this, assuming this link
survives email

https://drive.google.com/open?id=1B_Rgaomiru0DNmuTFUwZy-9q5p4SGo_L

Each app has a section, each section can be routed where you please. Each
section has a horizontal VU meter so you can see where audio is coming
from.

If you use pulseaudio then it owns the Alsa stack. You no longer
communicate with Alsa using the old apps. In the general case I believe
that alsamixer continues to work but I wouldn't bet on that for all systems
and all soundcards.

HTH,
Mark

Question, somewhat off topic but somewhat on topic.  I use smplayer to
send my videos to my TV using the second port on my video card.  I set
smplayer to send the audio to the TV, instead of my puter speakers. 
I've never used pulseaudio but with Firefox heading down that path, I
might have to switch.  My question is, if I switched to pulseaudio, can
I tell it that smplayer goes to TV and things like Firefox, Seamonkey,

HI all,

thanks for the repsonse.

I am using waterfox, which is not in portage. The mentioning of 
Forefox was onlu to make its heritage clear.

I already have some "experiences" make, when it comes to other things
for audio than alsa.

Background to my question:
I am still searching for a equalizer solution, which does not
uses the eq provided by the hardware (I am using a DAC, which
does nothing else, than converting PCM into an analog signal.
No processing whatsoever.

So the eq has to have some sort of DSP funktionality build in.

And it should be made for background processing.

Anu helpful alsa-based idea is very appreciated...

Cheers!
Meino

I think Matt makes an excellent point. The solution you're looking for
these days really
is pulseaudio, not Jack. pulseaudio handles multiple sound source
applications, can
route to multiple sound cards, and provides rudimentary metering so you can
see
what's going on. I have no experience using it on anything other than KDE
but these
days I feel it does a good job at what it's designed for.

Disclaimer, I do not use Jack.

Firefox builds, in my personal experience, are intended to be used with 
pulseaudio and only pulseaudio.  Some people have made some shims for 
making it worth with alsa, but they don't look sustainable.


As the other poster said, this endeavor is likely to result in 
frustration.  You may get it to 'work' for some value of that word, but 
depending on expectations, it may not be worth your while.

Personally, meaning my thoughts having used Jack for years, is that you'd
be asking for an insane numbers of problems and never ending
disappointments if you went this way.

That said:

https://jackaudio.org/applications/

at the very bottom of the page it does indicate that if you build Firefox
with custom build flags that it will connect to jackd.

A little bit of browsing makes it look (to my untrained eye) that possibly
these build flags were never fully adopted by the Firefox folks but as I
think this is an idea that's likely to produce more tears than joy I didn't
look very hard.

I use Jack every day on my system. Personally I'd never use it for general
purpose web audio.

Good luck, and if you do it let us know how it works.
