Mu-so connected to television dull sound



 I use the Mu-so as a way to listen to the sound of the television connected by an optical cable. Television is a Samsung. I am a little disappointed as I expected a brighter more pleasant sound. What I hear is a dull muffled sound. Does this sound familiar to you?

 Sacre bluer! I'm sure the guys at R&D also had that in mind when the product was being developed. Some sellers will tell you anything in order to sell their fish! 

I have read many reviews that state the Muso can be used as a "sound bar"and in fact the Naim website lists  "Digital Input (Optical) - Boost audio from digital sources such as TVs, set topboxes or games consoles"


I have not tried my Muso with a TV but it might be worth trying another digital source with optical out (Apple TV, CD etc) just to see how that sounds. If an alternative source sounds good it may be worth having a look through the Samsung manual in case it is pushing out some kind of Quasi surround sound or such like - that would sound like a car crash on the Muso. Although I think that is unlikely any TV would do that. 


Out of interest - is the source material 6ch or 2ch? Many TVs have an annoying trait of pushing out 2ch from their optical output - regardless of whether the source is 6ch or 2 ch. Possible that the fold down process is sounding messy on the Muso.

No worries, I hope you get it sorted. Will be interested to hear if you do and what the remedy ends up being. 

UK DVB Satellite carries seperate 2channel and optionally multichannel compressed sound tracks, and so depending on your what you have selected on your STB or TV the appropriate audio feed will be selected. On terrestrial DVB I haven't inspected the multiplexes and so don't know if these two formats are also present, but any attempt to create an MP2 stereo signal from an AAC/AC3 multichannel audio feed is going to sound pretty dire because of the lossy double encoding.



I had to change TV's from Sony to Samsung to get any sound over optical at all but my Muso sounds great with it.    The volume is variable from channel to channel which is annoying but the sound is excellent with a cheapo toslink cable.


After 10 months, I am becoming quite the Mu So warrior with the good tips around here.   I can stream Spotify and everything now.   I want to master UPnP with MinimServer and I will be ready to rock.   That may wait until Christmas when my help desk is home from school   Just stay at it and you will be surprised.  

I changed a few settings in the sound options of the Samsung television, paying attention to the 2ch vs 6ch options. Sound improved slightly though not overwhelming unfortunately. I'm afraid the quality of the Samsung might be due to the quality of sound I hear by Mu-so, although this Samsung belongs to the top range.

Thanks for your reactions!

@cdboy I'll check if the Samsung has variable output via optical.

@chrisSU PCM is indeed the option to choose. But my problem is not reduced volume but I find the sound itself is dull, treble is lacking. But anyway thank you for your reaction.

I've connected my sony tv via the headphone out (1/8") into my muso and the sound is incredible, so something must be wrong in your output settings. I haven't ever gotten round to trying optical out from the tv into the muso, because analogue sounds great!

The Muso is not a sound bar and I believe Phil Harris has confirmed that on this forum. For music I am sure all purchasers have been perfectly satisfied with this box but used with a television it is a compromise, at best. I knew all of this when I bought mine and linked it to my LG television and took quite some stick from my wife for its initial bugs and clunky connection controls. These have been mostly addressed and even my wife is quite happy with it. However, in its current construction, it is not and never will be a replacement for a sound bar.

I would not like the idea If the Mu-so would not give a proper sound when connected to my television. In Holland the Mu-so is advertised as a soundbar too......

As I mentioned previously, the naim website clearly states it can be used to "boost audio" from a TV. You should absolutely expect a decent stereo output from your TV through the Muso. I agree that it may not be a substitute for a good sound bar or indeed full 5.1 surround system - but you should see an improvement over the usual inbuilt speakers on a modern LCD set. 


If the website is incorrect and Phil has stated differently then i would suggest Naim update the website quickly as I'm sure many people would look at it as a one box solution they can play music on and run their TV through. More and more people have limited space now and look for convergence and convenience in their tech purchases. 


That said, I do not believe the website info to be incorrect - there is no reason why a muso is incapable of boosting sound from a TV.

I was not quite correct, the word soundbar was not used at the (Dutch) website. It stated, at the time I purchased the Mu-so, television sound is improved. As I said earlier the fact sound is not quite correct in my case could probably be due to a defect in my Samsung television. So far Naim is not blamed for anything.

Our MuSo is used as a sound bar 95% of the time and we are finally happy with it.  It takes a little commitment to get it right but it makes both music documentaries like 30 Feet from Stardom and Muscle Shoals, as well as popular movies like Django Unchained sound truly outstanding, and it is great for regular cable movies, music channels,  sports and original TV programming.

An update finally.. After comparing two Samsung televisions, same series but differing in size, experts concluded a different architecture in the audio part resulting in worse sound in my television. The Mu-so is nothing to blame as some of you had already suggested. I have to live with this until my next television arrives, which will take a few years.

I would like to thank everyone for your kind input!! 

Matthijs - What sources are you using through the TV - I ask because I do not use my TV to feed my sons play bar. I use a optical switcher box which my Sky DVR, Apple TV and Sony PS3 feed into and the single output feeds into my sound bar. 


I did this because my Panasonic TV does not push out 5.1 from it's optical output. If there is an issue with how the samsung are doing this then it may be possible to bypass it. You may have a sync issue as unlike the sonos, I don't think there is any audio delay settings on the muso - but might be worth connecting one of your sources (Blurry player for example) directly into the Muso to begin with a see how that sounds.

Harty601, thanks for your suggestion! Just by coicidence I had to connect two sources, Samsung Television and a Dune mediaplayer. I had to find a way and came across the optical switch as you suggested too. But alas there is no improvement as far as the Samsung is concerned. The Dune however with a large collection of music on the internal harddisk sounds good.
