OK, I dug deeper, to end the silence it's necessary to switch from /dev/dsp0 to 
/dev/dsp1 for each affected application, whilst there's playback from the 
application.

Then (confusingly) adjusting _either_ slider – /dev/dsp0 or /dev/dsp1 – affects 
the output.

Is this expected?

If I recall correctly: yesterday I _did_ get audio from at least one of the 
affected applications, whilst the notebook was docked. A Philips display with 
integral loudspeakers at one of the two DisplayPort sockets at the rear of the 
dock.


Which version of Firefox? Cannot reproduce over here.

Did you check the "mixer" controls, that PCM and Master volume is not zero.

r339929 no audio output to some sound devices with Firefox and some other applications

 for example:

- audible in Chromium, Falkon and Web
- silent in Firefox, New Moon (Pale Moon) and Waterfox.

HP EliteBook 8570p, integral loudspeakers.

If I recall correctly: yesterday I _did_ get audio from at least one of the 
affected applications, whilst the notebook was docked. A Philips display with 
integral loudspeakers at one of the two DisplayPort sockets at the rear of the 
dock.
