When I switched to hdmi2 today the display shows "PCM" for a few seconds, then displays the Dolby-sign and "PLII Movie". It used to show "Standard". What have I done wrong and what sould I do to fix it??

Hello, with the source playing press the display button on the remote. What format do you see? Thank you, CB

There is a small button on top when the screen closes it turns off the display. While the movie is playing press the small button with a small pointing object and see if the display shows something on the screen for a few second and then off (you can sometime see the movie playing but very dim). then there is a problem with the switch not switching the display back to normal. Hope this helps...

You must be using an HDMI cable to get Dolby True HD.

try different buttons

If the display is showing as optical/PCM, then the input signal is in 2 Ch Stereo.

Try to change the signal from the source i.e. the DVD player, On the remote, go to audio and press repatedly , the audio would change from audio1, audio 2 .... and so on, depending upon how may have been recorded on the DVD. If the DVD is recorded in Dolby Digital, it may show the audio as Dolby Digital 5.1 on you monitor. Once this setting has been done, your Receiver should automatically detect it and show as Optical/Dolby digital.

Please let me know if you you solve your problem.

In the menu is an option for switching master and true hd on. Standard its of and played als normal dts/dolby.

also: check the input (blu ray?): maybe it is set to only output no high def signals, so the amlifier doest recieve hd sound..

The best way to get Dolby sound working is to connect the components using the optical links.
As long as you are using PCM the Dolby sounds will never get to your system. It's switching the Dolby sound off as soon as it detects PCM. I think the only way you will get Dolby on is via a optical cable which should let you have bitstream.

I had the same problem with my 321 system. The fix is in the cable box settings. You want to change the Digital Out on the cable box..my choices were HDMI....Dolby Digital..and None. Choose Dolby Digital and it will show up on your Bose 321 display. I also have my cable box connected to my bose system via optical digital cable...and a digital coaxel cable from my dvr to my bose. Change that output setting on my cable box took care of the PCM 2.0 problem for me.

PCM is standard when using HDMI cables, you are passing an already decoded audio signal to the receiver and it outputs the sound and does nothing more. The reciever calls this PCM, your PS3, when pressing select should show that it is decoding the dolby digital HD. There is no quality difference in the two. PCM is the same because it is un compressed audio. So when using HDMI, no matter the signal that the movie or music is playing, wether it be dolby or DTS, you will see PCM when using HDMI.
