I am running Beowulf and I have all the audio stuff perfectly running
using just *only* ALSA (M Audio Audiophile 24/96 sound card, also
connected to my hifi setup, whit a real-time audio configuration).

I do not need any of the pulseaudio stuff (which is just a useless and
total mess IMHO... Indeed, I have removed all the pulseaudio packages).

Firefox, from a certain version onwards (sorry but I don't remember which
one), removed support for ALSA from the default build configuration
(maybe it will be restored in the future, I don't know if it has already
been but I don't think so), keeping only pulseaudio support.

This should explain why you didn't have audio on Firefox; while I can
assume that the other problems depend on pulseaudio and its configuration
(also because I seem to understand that they happened after you installed

The solution I suggest is to totally remove any pulseaudio stuff,
use ALSA instead, install the `apulse` package which is a PulseAudio
emulator for ALSA (this should ensure that Firefox -- and any other
program which require pulseaudio -- will work even if pulseaudio is not

Also I suggest to install some useful ALSA-related packages:
- `apulse`
- `alsa-utils`
- `alsaplayer-alsa` (and `alsaplayer-gtk`)
- `alsamixer` (and `alsamixergui`) to handle your audio devices
- `volumeicon-alsa` a lightweight systray volume control
