HTC 8S audio playback issue

[QuadraFX]

Talking about problems.. Do anyone have problem with camera when filming? For example, when I'm filming something once in time, white frame flashes for split second. Had this problem since 8.0.

I had this on 8.0 and since then I just gave up on filming with HTC8S, using my other phone, Xperia SP (well... beter quality and what is most important for me - really good stereo sound). I could check if on 8.1 it's the same. I'll share the result.
