I am going from my tv (LN32A330) via optical to the XDA-1, and with the volume at 0 when the channel gets changed, there is sound coming through my speakers. From the XDA-1 I go straight to my XPA-2. Anybody else experience a similar effect? Should this even be possible?
Also, does anybody know how to change the output of the digital stations from my tv to 2 channel output? I read that it defaults to multichannel and is not being decoded correctly (results in a hisslike sound).

Just got my XDA yesterday and only fiddled with it for about 10 minutes--haven't tried any source besides computer via USB. I may give the TV or Xbox a try this weekend just for fun, and if so I'll report back.
As far as 5.1 vs 2.0, that should be in your TV's audio settings. Go into the menu and see what you have selected for output--I don't think it's related to the stations unless you have an option that tells it to use whatever format the broadcast is in.

I figured that about in the settings, but I couldn't find anything. There is a setting for mono/stereo/SAP but nothing as far as 2.0. I guess I'll need to do some more searching to see if its possible. It would be a shame if I have to run some things separately from the XDA-1. |

That setting is utilized for if it is stereo audio that the tv is receiving. I know stereo is 2.0..at least I hope I do  Anyway, that setting has no bearing on the output with 5.1 signals. I chatted with a Samsung "expert" and apparently it will not output 2.0 with the digital stations  So now that I can't get my digital channels to run through the XDA-1, I am lost on where exactly to go with my setup. Ideally I don't want to run my receiver separately just to get the processing for the digital tv stations. Plus if I do that, I would have to run the XDA-1 through the receiver, which (from what I have read) is not as good as using the XDA-1 as the preamp. |

Ah ha! Is your TV being feed from a STB (Sat or cable)? The STB should have an option to output 2.0 vs. DD5.1- If your signal is OTA through an antennae, you may be out of luck.

Sadly, no STB...it is regular cable. At least this setup is only temporary, as I graduate in May and will be moving out of this place. At least now I know that whatever I go with for tv in the future, I'll want some sort of STB. While that part really irritates me, the part that I don't understand is how the volume of the XDA-1 being at 0.0 can allow any output whatsoever. This doesn't have much impact in larger rooms, but in smaller rooms where just turning the volume to 0 is as easy as muting it, I can find it being a slight issue. It'd be interesting to hear why this happens? I also found this to happen when changing inputs while the volume is at 0.0. So basically, whenever the signal drastically changes? |

I chatted with a Samsung "expert" and apparently it will not output 2.0 with the digital stations How do I put this...I don't believe you. I don't have a set top box, just cable straight to my TV, and have a very clear choice between mono/stereo/surround in my sound settings. Now, my TV is an LG so maybe this is something Samsung-specific, but I thought the choice for sound output was a very basic one. A quick search yielded answers saying the TV lacked a mixer and thus just passes on whatever format it receives, but I don't buy that since the TV only has 2 speakers (and thus would have no voices if you used them to watch a surround channel). If the TV's software insists on choosing for you, mixing to stereo without an output but forcing 5.1 for any type of digital out, that would be very unfortunate. Perhaps Samsung is a division of Apple. |

Perhaps Samsung is a division of Apple. I understand your questioning this. I have tried both mono and stereo, and both result in the same output of a hisslike sound. It may be Samsung only, but I don't know for sure. I did speak with the Samsung tech support (aka "experts") and they confirmed that the output is either 2.1 or 5.1, whichever is received. I don't know why it can't downmix this to 2.0, but it doesn't. ... Plus if I do that, I would have to run the XDA-1 through the receiver, which (from what I have read) is not as good as using the XDA-1 as the preamp. Have you tried this Receiver --> XDA arrangement? If so I am interested in hearing if and how well it works. Thanks. I have not tried Receiver --> XDA yet. That is a good idea as I'm assuming I can alter the signal to 2.0 from the receiver. I should have some time in the afternoon to try this and see if it resolves the problem. Thanks for the suggestion! |

Well for the TV's 2 speakers to output from a 5.1 channel, there has to be mixing involved. Perhaps it does this at the analog level, and doesn't have the ability to take a digital 5.1 signal and mix to 2 channel PCM before outputting.
It's a really silly omission though, because the circuitry to do so would cost them pennies. Your receiver should be able to do exactly that--just send HDMI to your receiver and take S/PDIF out, and it'll either be 2 channel PCM that the XDA will play, or you'll get nothing if it's in multichannel Dolby/DTS digital.

My thoughts exactly! Sadly, my receiver is a VSX-1017, which does not process audio from HDMI, but rather just passes through HDMI. It also just passes through a signal with the optical out without processing it, so introducing it into the chain does not allow me to go receiver --> XDA-1. It looks like my only options are to run XDA-1 --> VSX-1017 --> XPA-2 or alternately switching between the inputs on my XPA-2 for balanced/unbalanced. |

The reason I say that is because I had the same idea with my XPA-1s, and when I talked to Lonnie about it, he said to not do it as the switches were not designed for that type of usage. Having said that...There are users on here who do use their switches like that and report no issues. YMMV, and good luck with whatever you choose.  |

Anyway, that setting has no bearing on the output with 5.1 signals. I chatted with a Samsung "expert" and apparently it will not output 2.0 with the digital stations
