might not be your ssd or sound card, happened to me because the mumble overlay, so try disabling it.

also, try disabling steam cloud, but i don't know if these 2 things would help you with this specific issue, you don't lose anything trying.

My game has been doing that every so often, although I think my hdd is just getting old

.

You have the same problem vile had so talk to him about how he fixed his tf2

this happens to me too. it just crashes and plays the same sound over and over again. until i restart my computer.
