I've had a look on Google for advice on home cinema setups, but most seem to be for square rooms with the TV in the centre of a wall.

Unfortunately, due to the configuration of my living room (windows, doors and fireplace) the TV has to go in one corner of the room.

Does anyone have a link to a good guide on setting up a sound system where the TV is in the corner of a room?

As long as the front surround speakers are on either side of the TV then the positioning of the rear speakers is not that criticical. With any decent AV amp you can adjust the volume and delay of each speaker to compensate so that it sounds good from your usual viewing position.

I've seen some systems which have a configuration mic that will automatically setup your system. I assume they're doing automatically what you suggest in terms of adjusting delay and volume.

Are these any good?

Can't answer that as I am still using an ancient Denon AV amp which predates such fripperies.

My Onkyo 507 receiver has a mic and automatic set up. Best not to run it in the early hours of the morning if you've got awkward neighbours though as it does get a bit noisy

Basically the position of the speakers relative to the walls is not that important as long as you don't do anything silly like stick them right up at the top of the wall in the corners. More important is the position relative to your seating position and the TV.

In this Dolby set-up guide you'll see the layout diagram (it doesn't actually change for any of the seating distance options ) doesn't show any walls at all.

Click on the set-up you have/expect to get - 2.1, 5.1 or 7.1 as appropriate.

They are good in the respect you don't have to borrow/buy a SPL meter to set the speaker levels, where as a tape will do for the distances/delays, but it's very hard to set all speakers to the same volume by ear.

If you are lucky it may feature room EQ, this will take frequency sweeps in the room and sort out any dips/curves you may have.

We had a similar situation as our flat screen tv is in an alcove and the speakers are interested rear of the tv so the sound was awful!

After reviewing lots of speaker systems I narrowed it down to two, an Onkyo and a Bose one.

We had to buy from Currys as had a credit for their for a laptop they wrote off and they didn't have either of the ones we wanted!

I'm impatient and couldn't wait so we ended up buying a Samsung soundbar with a wireless sub, in all honesty its not really what I wanted but we've had it set up a week now and it's vastly improved the sound and it looks nice under our tv!

At first I could tell sound wasn't coming from the tv but now I've tweaked a few settings and it's sounds pretty good!

I've not ruled out getting another system at some point and will then give the soundbar to my son but for now I'm happy with it and the price was good!

Funny our room is just the same !

Usually its older British houses with this problem due to bay windows, square rooms alcoves and chimney breasts.

This is the best I could do.... Speakers are red (sub not shown but located next to front 3)

Its really hard to get the set-up right in these situations. Lots of reflection and constraints.

The sound is the best I can get from this configuration. The biggest problem is Bass reflection near to walls is terrible so the sub is turned down. If you stand in the middle of the room there is no bass - sitting on the sofas there is!

My Yamaha amp does a pretty good job at getting the setup distance and delay right however you will find these setups also create a sweet spot !
So some people wont get the benefit of the sound and it requires a bit more manual adjustment.

Unfortunately you won't be able to get the sound to the Ideal setup you see in Home cinema mags etc - most people have a family and more than 1 chair stuck in the middle of a blank square room

When we had a corner setup I found using di/bi pole speakers for the surrounds helped, adding the surround back speaker made a big difference too.

Auto setup will always create a sweet spot as it only does adjustment for one seating position, for multiple positions you really need room EQ, depending on the amp this can range from 2-8 seating positions. EQ helps with dips/curves in frequencies which really helps, especially if your room loads certain frequencies due to shape/furnishings which affect the acoustics.
