I think this problem is intermittent, sometimes happens, sometimes doesn't. On char login my char's sounds don't work, no horse footsteps, no spell noises, no pickaxe/ore mining sound, no axe/wood harvesting sound, but the other harvesting sounds render fine, and I hear all the other noises/sounds fine. This usually continues until another map loads, like a dungeon for instance. Sometimes when I wayshrine travel to a different wayshrine it starts working fine again, other times it continues to malfunction. Once the sound stops malfunctioning (works), it never quits again.
But here's the thing: I have an unusual sound card: Auzen X-Fi Bravura 7.1. That said, I believe they use Creative SB drivers, and what's more the symptoms point to something different than a problem with my particular sound card; not to mention this problem did not manifest until immediately after update 1.4.3. But looking at these bug reports I see no others reporting this sound malfunction. Please post if you had this happen to you, and report your soundcard type if any, please.
EDIT 9/30 (repeated below):
Just to clarify: The OP sound issues were in PvE solo (all over Tamriel), IDK about Cyrodiil.
I haven't noticed it inside a dungeon yet, the dungeon load seems to fix the prob.
And I'd guess it only happens (to me) about once in every 10 logins on the average, so it takes a lot of testing to see if it is fixed.
