I'm pretty sure I saw in this topic people complaining about the audio options on Blu-Ray... well as you can see from this article, at least Sony are doing something about it on the PS3 BluRay player.

From the article:

How exactly are things getting better? All BD's featuring material produced with high-def sound already have HD audio options. Most importantly, there is Linear PCM, which is what the original master is produced in and which is compatible with all HDMI based home theatre equipment, by definition. Then there is the IMO totally redundant losslessly compressed incarnation in form of Dolby TrueHD. Redundant, because it adds nothing, other than more effort at both the publisher and consumer end, for encoding and decoding. The utter stupidity of this is emphasised by BDs that have both a PCM *and* a TrueHD track.

Now the PS3 is getting the ability to decode another pointless lossless compression scheme, DTS HD:MA. Good for PS3 owners! Especially if they own BDs that feature HD:MA as the only HD track...

I would prefer if publishers just ignored Dolby TrueHD and DTS HD:MA and put only PCM tracks on BDs. At least in cases where there is enough space on the disc - so far every BD I've seen. Audio compression might be required if you want to squeeze whole TV series in 20 languages onto a single disc. But for movies - give me PCM any day.

As far as BD is concerned, Dolby TrueHD and DTS HD:MA are solutions in search of a problem.
