Yes turing on the "A" speaker is required for the Onkyo, but that only turns on the 2 front speakers in the "A" speaker jacks.
You may also need to check and see if the Onkyo has a menu selection in the setup menu that will turn on the sub woofer output on the back of the receiver.
I have seen on countless occasions where people just have a hard time finding that sub woofer option on their receiver.
I do not have the manuals for this Onkyo, so I can not tell you the exact way to find it.
I have been repairing surround receivers since they have been on the market and beleive me, you are not alone in this situation.
Sometimes it seems like you need a Phd. in programming or something similar just to firgure out how to set one of these up.
The solution should be in your owners manual, with the problem then being, just where in the manual. Go slowly thru it paying the closest attention to anything about set up procedures.
I have also seen at times where the setup for the sub-woofer is not listed as sub-woofer, but as "LFE" (low frequency effect) . So keep your eyes open for that.
something else, your sub woofer may have an auto turn on. That means it will only turn on if it detects an input signal. Make sure yo uhave the volume up enough on the receiver to trigger that auto turn on if yours has one.
I would like to have been more help, but without the manuals I can only give you general type thngs to look for. These type of receivers are all so different and all so complicated to operate. The days of just turning on a stereo, selecting your source and turning up the volume seem to be over.
Let me know if you need any more assistance from me.
p.s. Very nice system you have, when you get the Kef working I think you are going to just love this system. and Onkyo has the best quality receivers in their price range.

Also, it could possibly the preout terminal itself that is not working. One way to prove that is by transferring the subwoofer cable from the preout and temporarily transfer it to the tape out section. If it ouputs sound from there, then that means the speaker and the cables are working fine and it's just the preout terminal itself that is not picking up anything. ^_^

Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.

SOURCE: Onkyo TX-SR705 Muting Problem
if what Dark_Orbit said does not work try doing a master reset by ressing and holding the dvr/vcr button and stand by button simultaneously. This would erase all your assignments so you would need to reassign all your sources hooked up to your onkyo.

Onkyo receivers have a safety circuit in them to protect the Amplifier from blowing up:
If you listen closely when it shuts down ( after a loud scene ) there is likely a loud 'Relay Click'..
If this is what is happening you might be able to verify it by turning the volume all the way 'off' and waiting for the circuit ro reset ( releasing the safety relays & returning power to the internal Amplifier ) : you should hear another click, yhen you can bring the volume back up carefully and there will be sound again.
This safety circuit trips when then Onkyo receiver detects an 'Over Current' condition on the
' Power Supply ' that feeds the internal 'Audio Amplifier'..
Generally caused by:
Improper load presented to the Amp outputs ( FL, LR, RL, RR, SUB, CENTER )
If you can ( one at a time ) turn off the SUB, Center, Fronts and Rears: trying to re-create the failure each time while you have one part of your system disabled or having their level turned way down..
You can isolate where the problem is coming from.
- any or all of these speakers being the wrong Impedence ( I.E. 4 Ohms instead of 8 Ohms )
Unless the receiver manual or the sticker near the 'speaker connetor' specifies a range or another value, you should assume 8 Ohms. Your speakers should say on the back of them.
- any of the speakers being connected in parallel ( 2 speakers to a single one speaker output ) .. Two 8 Ohm speakers connected in parallel make a 4 Ohm load to the amplifier.
- If the Suwoofer is Passive ( Not having its own power cord and amplifer ) it has a
Passive Crossover : this crossover can have its own power rating or limitation.. If it is constructed with capacitors that have too low of a working voltage, then they can saturate and the crossover itself can present a load to the amplifier that will case this 'Over Current Shut-Down'..
You user manual should detail this.
