after deleting .asoundrc (that was used for selecting a usb soundcard)
and changing the order of sound cards as here
https://wiki.archlinux.org/index.php/Ad … sound_card

the sound would play.

All you need is alsa-utils, alsamixergui and apulse to make FF play sound with alsa.

The firefox-esr packages supplied by Devuan do not need apulse to produce sound with pure ALSA.

[. All you need is alsa-utils, alsamixergui and apulse to make FF play sound with alsa.

Good luck, rolfie

Thank you very much, forgot quite about apulse.

on devuan jessie it is not available, but on beowulf i could install it;

however, the audio would still not get through.

i have tested now a bit with devuan jessie and beowulf,
and it seems that the

alsa

package is missing on both distros.

There is no alsa package, I think there never was. In older Debian versions a package alsa-base did exist, but this is depracated now.

ASCII shows:

# apt list alsa*
alsa-firmware-loaders/stable 1.1.3-1 amd64

The list on Beowulf is similar with newer versions partially. All you need is alsa-utils, alsamixergui and apulse to make FF play sound with alsa.

Good luck, rolfie

i have tested now a bit with devuan jessie and beowulf,
and it seems that the

alsa

package is missing on both distros.

some things don't seem to function as they would on an older distro like

which is alsa-only.

when i try to playback audio in browser from this site here

http://www.gaia.com/

it would not play on my alsa-only devuan computer;
however, on the same computer, running lubuntu 12.04, the audio would play.
something is probably missing on the alsa-side, but i cannot see how to install the packages from the repo as alsa seems missing altogether.

dpkg-deb -x file.deb /output/dir/here

You would probably have to add the extracted library path to ldconfig. So you would probably need a file, /etc/ld.so.conf.d/my-customized-firefox with contents:

/output/dir/here/usr/lib/

And then run ldconfig.
DISCLAIMER: I have not done this, and officially you shouldn't be doing this at all, for several reasons: 1) Super-old firefox. 2) Customizing your ld path is something you should do when you really, really know what you're doing and if you did, you probably didn't need our help for this task.

is is possible to download the .deb for firefox-esr 52 with alsa enabled?

Not recommended though, old versions of FF are riddled with known security vulnerabilities. Your system will be wide open if you run those.

@rolfie: the Mozilla FF versions are not compiled with --enable-alsa. And they have user studies (embedded spyware) enabled by default, unlike the De??an packages.

thank you for your help!

is it possible to

extract the contents of .amd64 deb file locally to achieve something like a local portable copy of firefox-esr instead of installing it directly onto the devuan/debian system?

it seems the firefox 68 provided by devuan is functioning with alsa only!

.

however,

on youtube it would not enable sound on my box beowulf with OpenH264 Video Codec?
i am using viewtube extension.

the firefox is 68.5.0esr (64-bit)

Forget Firefox 52, Basilisk will give you the same experience but with security fixes and improvements across the board.

thank you very much!
this seems a quite promising legacy browser!

hope it is also a safe one!
the only alternative to firefox seemed to me seamonkey, but some add-ons are not compatible with seamonkey.

i still use this older guide here to remove pulseaudio with alsa

http://linuxg.net/how-to-properly-repla … n-squeeze/

problematic only is alsa a bit when i try to use an external usb soundcard, as it requires some effort to get this soundcard working;

with pulseaudio it is more elegant, just by installving pavucontrol one can easily manage several soundcards.

thank yo very much for your help.

today i downgraded to devuan jessie on my t60 laptop (the newer devuan/debian seems no longer to offer icedtea-plugin for java, needed for some playback on older websites)

now i have firefox 68.6.0esr (64-bit) ESR quantum? release

is it possible to use this browser also with alsa-only?

i don't think  i will be able to use basilisk on here with devuan jessie;

normally i use firefox 52 esr + seamonkey + chromium (for netflix)
but the firefox 68 seems quite fast and most of the things i need seem to function.
sadly, the older plugins won't function, but quite a lot of add-ons have already been updated or adapted.
