I have a Samsung 6-series 46" LCD. Using the tv's speakers, for now. Everything has been fine till the last few days. I got a new PS3 super slim and suddenly, Blu-Ray dialogue started to be incredibly soft (wasn't an issue with the first PS3 I had). I saw in the PS3 SELECT controller option that the PS3 is outputting 5.1 sound, when I have specifically selected 2-channel Linear PCM sound (44.1 and 48) in the PS3 setup menu. I believe this is why movie dialogue is so incredibly soft.
As it relates to the Samsung, I have found a workaround, though not ideal. When I go into AUTO VOLUME in the Samsung sound settings and select NORMAL, it seems to raise the dialogue level, while keeping the sound effects from blasting me away. It's an artificial way of getting more dialogue, but sad that I have to resort to this.
Anyone else use the Auto Volume to deal with PS3's/Blu-Ray players that output incredibly soft movie dialogue?
Also, today I have exchanged the 3-week-old PS3 superslim for a new one and hopefully it will output only 2-channel Linear PCM to the Samsung and not try to go for 5.1.
A Cox Cable tech 'hot-swapped' HDMI cables on my PS3 and cable box recently and hope this didn't cause my issues. Seems unlikely but who knows. I'm starting fresh now, with the new PS3.
