Windows 10: 5.1 surround sound intermittently switching to stereo and back.

Hi,

Hope you guys can help as I couldn't find anything helpful on the web.

My issue is that while playing any audio in surround sound it will randomly switch to 2 speaker stereo and back. My setup is as follows:

Windows 10 Home
intel i5 processor
Nvidia GTX1070 gpu
outputs to a sony ht-rt5 home theatre connected to sony bravia tv

output is through an HDMI cable going to the HDMI-ARC port on the ht-rt5.

have tried updating drivers, changing hdmi cable, enabling/disabling output devices and anything else I could find on the web but no success. Haven't even seen a thread with a similar problem yet. Any help would be much appreciated.

:)

 

5.1 surround sound

Just upgraded to latest Windows 10. Surround sound is not on audio channel menu. Only "stereo" is listed. Surround sound is also now not working on ONKYO receiver. Windows says I have latest sound driver.

All other help messages talk about realtek. I just have what came with Dell computer.

 

Good surround sound headset

I know you say you're not that guy, but stepping into the $250+ range really brings a change in build quality that might have you never having to buy another set. Otherwise, getting 6 speakers with decent sound in a headset is hard, and that's what you are asking for, and I have no suggestions, but just a bump up the list. *Stick Out Tongue

 

Intermittent Beeping Sound

Before I elaborate on the steps taken so far, allow me to notify you that I have done research on this issue via the internet. Armed with the suggested solutions, I then:

1) Clicked on the 'Start' button, followed by 'Settings'. Then on the 'Settings' window, I clicked on 'System' followed by a click on the 'Notifications & actions' On the right pane, I set the 'Get notifications from apps and other senders' switch to 'Off'.
No changes were made but it had no effect on the intermittent sounds.

2) I then added the 'Get tips, tricks and suggestions as you use Windows' and disabled it. Again this did not help at all.

3) I then enabled the switches for both items back to 'On'

4) Clicked on the 'Start' button, followed by 'Settings'. Then on the 'Settings' window, I clicked on 'Devices' followed by a click on the 'USB'. I then set the one and only switch to notify me if there are issues connecting to USB devices to 'Off'. Again this
did not helped as the intermittent sound still occurred. I therefore set it back to 'On'.

5) I clicked on the 'Control Panel' (since I enabled that icon for my desktop), followed a click on the 'Hardware and Sounds' item. On the next page that appeared, I clicked on the 'Change system sound' item. Then on the 'Sound' window, I selected the 'Sounds'
tab. A list of system sounds appeared under the 'Windows Default' and I moved the cursor to the 'Device Disconnect' item. I then set the sounds associated with that event to '(None)'. The 'Apply' button was pressed followed by the 'OK' button and closing of
the 'Control Panel' window. The intermittent sound did not occur anymore. However, since I set the sounds to (none), I WILL NOT be notified whenever a device is disconnected and this is what is causing a problem - I prefer to be notified.

Hopefully you would be able to suggest a better solution. BTW, this problem did not occur initially. Only when the Windows 10 updates were applied recently (about one or two months ago) did the problem surfaced. This was the reason why I suspected that the
updates was the culprit...but I could be wrong.
