When I use the input selector, the video signal switches just fine, but all audio playing into the amp is always played out from the loudspeakers.
For example, if I have a DVD playing in my DVD player, then press play on my CD player, both will be output from the speakers, even if I have the input set to my PC input channel. Weird, broken, or a 'feature'?

Re: Audio selector does not mute unselected inputs
There is a matrix switching IC on the circuit board that switches and routes the sources. This IC (for the audio) may be damaged, or it is not being properly commanded by the uPC controler. You will have to send the reciever to a qualified service tech to have this verified. Troubleshooting this can get involved if the fault is more than just the matrix IC.

Is there a mute setting or another input mode set on the tuner/preamp? If not and there are no other inputs connected to your head unit, then it appears that it is fubar.
Hopefully there is nothing wrong with your separate amp other than needing a signal to amplify.
A typical stereo receiver / amp consists of switching low level input signals (CD, DVD, Phono, DAT, etc.), processing them and then output to the amplifier (low level) input for amplification to levels needed to drive speakers. The low level signals would barely be audible via an earphone, so they need to be boosted significantly in order to drive speakers.
Some amps provide jumpers to insert into the phono jacks on the rear of the amp to bridge the processed low level output signals into the low level amplifier input. You could install a Y cable here to feed two amplifiers - or - connect a tape recorder's "REC L+R" to the low level output and the "PLAY L+R" to the low level amp input so that you'd hear the actual audio as it had been recorded on the tape.
If you remove the jumpers (or tape recorder if used instead), there is no way for the low level audio to get into the amp's low level inputs for amplification.
There are two ways of connecting to get cable TV audio from your Home Theater System. 1) If your HD cable box has a digital audio out ( either optical or coaxial ) you can connect this to the Samsung Home Theater Systems digital input. While watching a TV channel scroll through the Samsungs input ( source ) selector till you hear the sound. Remember to mute the TV sound while you are doing this.Most probably it will be the CBL/SAT input or Video AUX. 2) If your HD box does not have digital audio out you can connect the Red & White audio out of the same to your Samsungs Aux or TV or Video audio inputs . Ignore the yellow socket and connect only the Red and White audio inputs.For getting Video through the TV connect the HD box to TV via HDMI cable or connect the Yellow video out to the TV's Yellow video in. I am sure it is already connected .
All systems with multiple audio/video inputs for each connection must be told what connection you want it to play. Most likely your selected choice of input is set to an input other than digital. I included a link to download the manual for your Kenwood model; see page 9 for "Input mode settings".
First use the input selector knob to select the input you are using for the blue ray player, then press the input mode button to select digital auto; the Kenwood should take a few seconds to switch over and then you will be in business.
Make sure that the DVD player is connected into the correct inputs on the receiver and that the receiver also has the correct input selected to play. If your TV also has component video inputs it is best to connect the player directly to the TV. Otherwise, make sure you have the TV connected to the receiver via component video out.
Each CD Player has audio out put amplifier circuit and this output amp remains Mute until it receive signal to out it. While using Y-Connector, when you try to listen one player sound, other goes to Mute as its in Stop position and caused to minimize the out put of other player which is being played. That's why you listen good sound if just one is connected. If you want to connect both players at one amplifier, you need at-least 2 inputs in amplifier and since your Fisher amp has not 2 inputs, so I suggest to buy another amp equipped with 2 or more inputs. Hope this info will help you.
If your 2100ES has a selectable INPUT AND OUTPUT and if you're intending to send all signal to the power amp, i.e. not bi-wiring or using the 2100ES to run mid-range or treble then you simply send Left & Right audio (White & Red cable) from a 2100ES output, probably AUX OUT ( it doesn't really matter apart from Phono on some units) straight to the power amp on AUX IN.
We should be just dealing with audio here, so connect the NAD audio output to CD or DVD IN. Select CD or DVD IN on 2100ES input switch and switch output to AUX OUT (whatever you decided goes to the power amp) on the 2100ES. Turn power amp to AUX IN and it will now get an audio signal from the 2100ES for amplification.
Speakers connect to the power amp as a normal amp, so pos and neg etc. The 2100ES now only acts as a signal feed, the power amp does all the work.
So, summary - switch on the NAD, press play - video goes separately and audio goes to the 2100ES. Turn 2100ES to INPUT for NAD. Turn 2100ES to OUTPUT allocated for power amp. Turn INPUT on power amp to allocation for 2100ES.
TRY PUTTING A SET OF PHONO CABLES INTO THE VCR INPUT THEN TO THE ANALOG OUT PUTS ON TOUR DVD/VCR SWITCH AMP TO VCR PRESS DIGITAL INPUT BUTTON ON FRONT OF AMP UNTILL YOU GET _ _ _ SET SOUND TO PROLOGIC 2.THIS SHOULD WORK.
