Hey guys,I planing to get TOSLINK connector for my dad 5.1 home theater dolby digital,hows it sound like is you use astro with dolby digital does all channel support it? like
tv3?
Dolby 5.1 on Astro is only available on selected HD channels only. SD channels are only Stereo/Mono.
The surround sound are great, especially from movies channels like HBO and Fox Movies. Remember to change Digital Audio Settings from your Astro box from Stereo to Dolby Digital 5.1, but do note that this will result your RCA output from Astro box or TV (that do not support Dolby audio passthrough) to have no sound when the channel is Dolby 5.1 (e.g. HD channels). If this happens, you got to switch back to Stereo, and you shall switch to Dolby 5.1 only whenever you want to enjoy surround sound.

5.1 audio for TV3 is not yet available on Astro, now it is only available on digital TV platform.
TV3 (HD) now uses HE-AAC codec for 5.1 audio, no longer Dolby audio codec. If the audio is 5.1 but it's not AC3 or E-AC3 or DTS, using Optical audio (TOSLINK) will not output as 5.1 surround audio, even if your setting has been set as "Bitstream". The best option is use HDMI (ARC) method to output 5.1 audio instead of using optical cable. For nowadays, optical cable is used only if your home theatre system (especially older ones) do not have HDMI input, to enjoy surround sound. You can Google more about this, if you're interested.
