Bugs are still cropping up on the World of Warcraft Public Test Realms. But then again, that's what it's for: to identify bugs so they can be fixed by the time the next patch rolls around.

Of course, not every bug can be isolated and fixed in time. A recent thread on the official WoW forums reports that sound problems are still showing up on the PTR. According to thread creator Grimfang, some casting sounds are not playing. Other forum members have also chimed in, reporting missing now sound, gun sound and even pet sounds.

According to Blizzard poster Tigerclaw, the dev team is aware of the sound issues. While there have been some improvements in patch 2.2.3, work will reportedly continue in post-2.2.3 releases, continuing on until patch 2.3.0 hits. Hopefully these problems will have all been remedied by then.
