Just a note, they are still there (I know, your patch notes say it's not completely fixed).
If it will help, I was playing just fine with no texture problems until I had to log out/log back in because a quest wouldn't advance (didn't fix that problem, but oh well). When I logged back in, pink textures everywhere. Needed to go to the 32-bit client to play normally.
I also get some of the sound stuff; it's not the white noise (yet) but I've noticed music stop playing until I relogged, for example, and voices cutting out.
For reference, PC specs:
Win 10 Pro 64-bit
AMD FX-8350 (8 core) at 4 GHz
GeForce GTX 960 2GB video card
1 TB regular Hard Drive
Server is PC/NA. I also repair after big patches; I've done so twice since 2.3.7.
