Dolby 5.1 playable? Iriver H120

<< < (2/3) > >>

Chronon:
ad2003: Regarding codec, isn't Dolby Digital == AC3? 

saratoga: Is it generally true that the data that comes from optical out is 16-bit PCM (either mono or stereo) with sample rate corresponding to the source files?

saratoga:
I have no idea how the optical out works.  I never had an iRiver player.

Vchat20:
Generally speaking when you are feeding a receiver via optical or coaxial connections, you have a choice of 2 formats: 2 channel PCM or multi-channel AC3/Dolby Digital (there are other's like 'TrueHD' and such, but for the sake of confusion I'll leave them be. They are primarily focused on blueray discs and only the most recent receivers support them. There is also a 'WMAPro' multichannel codec that 'some' receivers support, but I'll also leave that out to save headaches.). While it is possible to re-encode them on the player with some handy work, rockbox currently does not support this (there are a number of variables involved here. Needless to say I have high doubts rockbox even remotely supports transcoding of this nature considering it's focus on stereo audio/music playback).

So your best bet would be to either leave it as AC3 or transcode it on your computer if it is not already. Then just jump in and play it back on your player and see what it does.

ad2003:
Hi -
ok, thank you - I still don't know, which fileformat I could try, but I will check it out, soon.

thanks for the answers!

saratoga:
If you don't have dolby files and don't know what they are, why exactly are you curious about playing them?
