HW-N950 - Solutions to common problems

Hi everyone,


After some trial and error and searching of forums here are some solutions to common problems and questions of users of N950.




The overal bass volume from subwoofer and its quality is VERY dependent on the subwoofer placement in your room. You need to check different locations in your room for subwoofer placement. There is a general "golden rule" of subwoofer placement - corner of the room. I found the sweet spot for the placement in front left corner room between wall and the cabinet (of course for you it may be completely different place). After checking four different locations in my room, I found out that the bass is louder when the speaker of the subwoofer (side with the cloth on it) faces an obstacle (cabinet). When subwoofer was facing open area of the room the bass was very subtle. So the subwoofer is not weak , with proper placement it can sound very loud and deep for every sound source, not just for ATMOS sources.




Finally, I have managed to connect to Smartthing app after several fails. Here is what I have done:


1) I have powered down my wifi router and N950.

2) Powered on my Wifi Router back, waited for wifi network function to be operational

3) Powered on N950. I checked if every speaker was connected.

4) I switched the source to WIFI on N950. Display of N950 showed WIFI NEED TO CONNECT

5) I pressed and held the Network button on the bottom of the N950 for couple of seconds  - display showed WIFI NETWORK

6) I runned the Smartthing app, the N950 was seen by the app, so I tapped to add it.

7) After couple of seconds dialog appeared with my wifi network name and password to be added.

8) Filled my Wifi password and the app finally added N950 as a device.




Just hold OPTIONS button (gears) on your remote controller for more than 5 seconds. Then press left / right to access frequencies and up / down to boost or cut. If nothing happens, try to press and hold the button once again. I really recommend to play with EQ as it improves the overall quality of sound. With proper subwoofer placement you will get deep bass so you will maybe need to enhance highs and cut little bit mids. My preference is is to cut 1.2KHz by -1 and then bost 2.5KHZ by +1,      5HZ +2     and    10KHz +3.


4) CALIBRATION, LEVELS - basic SOLUTION for 7.1 (not for 7.1.4)


This can not be done just by the soundbar itself. You need to have microphone and SPL meter. For very simple solution you can download SPL meter app for your mobile, and then either use phone microphone (less precise) or connect your phone to an external microphone. For sound reference level I used DTS HD Master Audio Sound Check 7.1 video:


Copy the file on USB and play it either via XBOX ONE S/ X (I used VLC app for XBOX ONE) or PS4, or any device capable of decoding the video and 7.1 audio. Set your audio output to Bitstream out - dolby ATMOS, or uncompressed 7.1.


Put your phone or microphone to your listening position. Adjust the overall volume level to 13 or more depending on your room size. Be quiet, close your windows, turn off everything which produces sound (send your wife shopping, and kids outside :-) )


Then you have to write down average level of every speaker level when playing white noise sound from the video (follow video instructions and write down average levels shown in SPL meter app). Do not bother with subwoofer level, it is hard to do calibration of the subwoofer this way.


You may need to repeat the measurement process several times (4-5 is enough to minimise errors) and then make an average of your all measurements for every speaker (excluding subwoofer)


I have got these results (this is valid for my room with dimensions of 3mx5m and my rear speaker placement on back sides of my couch, very slightly behind of my listening position on both sides):


CENTER speaker is +1dB louder than FRONT LEFT and RIGHT. Surround speakers are louder +2dB than FRONT LEFT and RIGHT. The SIDE speakers are very loud, almost +7dB then FRONT LEFT / RIGHT (probably for sound to be able to bounce from walls/obstacles).


So if you want to sound channels to sound approx. equally then you need to cut those speaker levels by measured difference vs. FRONT LEFT and RIGHT. (in my case to cut CENTER by -1dB, REARS by -2dB,...)

However, by cutting SIDE speakers by -6dB (this is max you can do in N950), the surround feel of side speakers is less hearable, so its your choice how to cut the level. I decided to cut them only by -2dB).


This is only very simple approach of calibration and only for 7.1. You can not measure the four upward firing speakers this way, as the test video is only for 7.1. If someone has 7.1.4 audio test with white noise samples, please post a link. 



For info, my N950 is running FW 1001.2 as a factory default. I decided not to update to 1001.3 as some users have problems after the update. You can switch off auto update feature in Smartthing app on main screen.


Re: HW-N950 - Solutions to common problems

Just to add to 2 above: I wasn't able to connect the soundbar to wifi when using the SmartThings app. I tried all the suggestions in the various forum posts I came across and still wasn't able to connect. By accident, I managed to get the soundbar connected to wifi. It turns out the SmartThings app running on Android 8.1 did the trick. Initially I was trying with the SmartThings app running on Android 9. So if you are running into this issue and using a device with Android 9, try using a different device with a lower Android version. Once you are able to add the soundbar to the SmartThings app you can go back to using the SmartThings app on Android 9.

very complete your review, thanks. what is your best setup for Dolby atmos?


Re: HW-N950 - Solutions to common problems

Hi this may help someone. I too had very little bass. Then I found a speaker placement document for the N950 with recommendation of placement and distances and where sub should be  (this is not in manual). just search Samsung n950 speaker placement and u will find it. I had my subwoofer all over the room but always in a corner and it was non existent didn’t get any bass. So I searched and eventually found the document and trust me this made a big difference compared to the bass or no bass I had before. By no means is it enough but it’s way better. 


Recommended speaker placement
• Floor (listener plane) speaker height/soundbar height should be at your ear level when seated, typically 3.9 feet (1.2 meters) from the floor.
• Subwoofer should be on the left side, slightly in front of the soundbar. Pair subwoofer and surround speakers as part of your initial setup.
• Surround speakers should be approximately 3.3 feet (1 meter) behind the listener, 90–110 degrees from the center of the room.
• Speakers/soundbars with Dolby Atmos-enabled speaker elements should be placed so an upward-firing driver is no lower than ear level and no higher than halfway up the wall. Ensure nothing blocks the audio path of these upward-firing elements.


hope this helps. I had not seen anyone mention this online. 


I am running the latest update. So far no issues to report. 




Re: HW-N950 - Solutions to common problems

Hi i have just got my n950. My issue is too much bass. When watching terrestrial tv on sky q with dolby digital plus set on it the bass is quiet with sub set to +6.

Watching jurrasic world in dts x on 4k blu ray i have the to put the sub down to -12 and its still shaking the house down. The sub is on the right corner of the room. 

Anyone help me otherwise im gonna have to send it back as its got too many extreme issues for my one bed maisonette and neighbours to cope with?


Re: HW-N950 - Solutions to common problems

This may be helpful, pink noise for all kinds of setups, atmos channels included:,-Downloads-u...


I have a question here, if I may. I will get the soundbar the next few days. My room measurements are 3x6.9m, height is 2.3m. 

Soundbar/TV is positioned in the middle of the 3m wall, satellites on the other 3m wall. Sitting position is about in the middle of the room.

Now, can I mount those satellites only at ear-sitting height, or can I (preferably) mount them at ear-standing height, and if so, then point them downwards to the hearing position? 


thanks a lot!



Re: HW-N950 - Solutions to common problems

WIll add another solution. I experienced crackling/static noice during playback from all speakers and started thinking I got a bad unit. Ater trying countless suggestions, I pinpointed the cause of the problem – turned out to be the audio driver that comes with NVIDIA graphics driver installation package (I use a PC as the source for video/sound, and HW-N950 is connected to my PC via HDMI). So, if you use PC in your setup and an NVIDIA graphics card, try this solution:

1) Go to device manager > Sound, Video and Game Controllers > NVIDIA High Definition Audio Device.

2) Right-click it, and select Update Driver.

3) Select Browse My Computer > Let me pick from a list of available drivers on my computer.

4) Ensure the Show compatible software check box is selected, and then select "High Definition Audio Device" (note: without "NVIDIA" in the name).

5) Install the driver and reboot.

6) Check the driver version for this device (after installtion it will not have "NVIDIA" in the name). As of 20/02/2019, I use driver signed by Microsoft, dated 14-Sep-18, driver version 10.0.17763., which helped me get rid of crackling in all scenarios. 

Hopefully, someone will find this useful, because I read reports about crackling in a number of reviews. Hopefully, NVIDIA will address this. Whenever, you are going to update NVIDIA drivers after this , you may need to skip installation of the audio driver (or install it to test it, and then reinstall the older driver from Microsoft if the issue is not fixed yet). 

Curious note: If I go to the properties of the audio device in Windows sound devicesm, on the Supported Formats tab, the info is a bit different depending on the audio driver installed: with the older audio driver mentioned above (that does not cause crackling), there is additional bit depth (16, 20, and 24), and Atmos in the list of supported sound format is listed as Dolby Atmos (Dolby Digital Plus), Dolby Atmos (Dolby MAT 2.0), and Dolby Atmos (Dolby MAT 2.1), while with newer NVIDIA audio driver, the bit depth lists only 16 and 24, and in list of supported format Atmos is mentioned only on one line (without mentioning its MAT subtypes).
