Bug Description

Playback of Blu-Ray video discs with the PCM audio track selected is accompanied by either a high pitched tone or high pitched noise, i.e. what either sounds like a single clean frequency or what sounds more like a mash of frequencies. It's not a problem with the system per se (nothing else causes such a noise), nor with the discs (happens on two different ones).
The PCM audio streams I tested are sampled at 48 kHz and 32 bit. Very infrequently, the PCM stream will actually play without this noise, but as soon as I seek in the stream the noise is back. One disk also has a dts-HD stream, which also plays fine.

With no sample, no log and very little technical infos, I am afraid there is not a lot to do about this bug report...

I cannot currently do any kind of testing, but I'll try and upload a few seconds of audio from one of the offending discs
