As someone pointed out earlier there are several separate sound issues. For me, two of them were fixed with todays update.
- No sound when disconnecting earphones.
- Crackling sound when streaming flash hd video.
There's the 3rd problem.... anything played through the built in speakers suffers from too low a left channel, a louder but still inadequate right channel, both channels sound like the speakers are blown. I've only seen a few people with this one.
But remember, this is still under warranty and the online and voice support was excellent for me. They walked me though some determining steps and then authorized me for a replacement. If you guarantee with a credit card, they will ship you a surface 2 without having you ship your current one first. You then have 14 days to send back the surface that is broken. And after having had an Asus tablet for 3 years, this support process is 100 times better than Asus ever was! I'm pleasantly surprised...!
