Sound stopped working for il2 4.10m

[furyfighter]

the title more or less sums it up, i did a complete fresh install of il2 1946 from the disk then patched all the way to 4.10m barely 2 weeks ago. I played online a few times and offline a few times without issue untill last night when i loaded up an online dogfight game. I had no sound, all my settings were exactly the same but there was nothing to be heard.

Fearing my sound in general had just died i tested other programs and they work fine, youtube, videos on my pc and even other games play thier audio normally. I've also checked to see if my sound drivers were obsolete but i am asured they too are up to date. Is this a known issue, or if not, what can i do to fix it, no sound is kind of a huge detriment to the flying experience for me
