Anyone else losing Audio?

Just curious.....last night after being logged in a few hours....I suddenly lost all audio streaming. This happens sometimes when I've been on for a while and usually re-logging fixes it.
Well...I came back on today after clearing my cache and still zero audio of any kind. I double checked my Windows control panel to be sure it hadn't got muted accidentally (this happened with one of the last WL updates) and it's on..... all my settings in SL are as they should be too. But....eerie silence is all I get. LOL I'm running WL...so maybe it's just that version with the glitch, just wondering if it is also 'just me' LOL

This is probably a silly question but...

Does your audio work outside of SL?

I have had this problem in the past. I will just suddenly lose audio. I'll do all the normal things, like go to preferences and uncheck "audio" and then check it again, go down to the symbol on the main screen - turn off audio (if I hadn't done that yet) and turn it back on, and the audio will still not play (this "trick" seems to kick the stream into working).

Then I'll log into an alt and my ears will be blown off (do not turn up volume to really high settings trying to get audio to work ), because the alt's audio works. So I'll log off alt, log into the account that is having problems and . . . exact same land, exact same settings, and can't hear audio.

Annoying problem.

Edited to note: The problem is one that I've had with regular viewer and with Windlight.

I had this issue today while teaching DJing. WHen I turned the radio channel it would clear up but audio would fail once again in a few minutes. The students experienced it also. Was similar to a stream buffering.
