Hi
On my 64bit TC, Ungoogled-chromium has sound working good.  But it is only version 115.  My bank requires version 116 or higher.  So I cannot do online banking with Chromium.  And I worry it is too outdated.
So I installed firefox-ESR.tcz, which is version 128-ESR.  This version is supported by my bank.  But sound does not work in firefox-ESR.tcz.  How do I get sound working?
I have alsa-config.tcz and alsa.tcz loaded.
And here is my .asoundrc.  I set card #1 as default.
tc@box:~$ cat .asoundrc 
pcm.!default {
type hw
card 1
device 0
}
ctl.!card1 {
type hw
card 1
device 0
}
defaults.pcm.card 1
defaults.ctl.card 1
Btw, sound also works good when I play MP4 in Mplayer.
Any idea how to get sound working on Firefox?
