Thank you for checking. It is really odd. It used to work for me though. Just not now.

I have used Firefox, IE, Chrome and Edge. 

If I send an email, can I just place a link to this forum so I do not need to explain it all over again?

I will uninstall and reinstall as you suggest.

Hey chazzx, never knew about this Online COX TV website.  I tried it from my W10 Firefox and it worked for viewing and for sound on various channels, including my STARZ.  Did not try specific TNT, WGN....However, when I exited the tab, I could not log back on.  Not sure if browser needs reloading.  I checked my ID/pass a couple of times.  This site could be useful for phone apps and computer, where TV is not available...

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

letti001.....maybe the sound icon on the bottom rt of the COX TV window is set to mute or the slidebar is  low or you have mute on the computers audio.  I had the TV window sound on mute originally.

I tried restarting Firefox, and finally restarted my computer....no luck, cannot re-logon to watchtv.  ID/pass, who knows...must be on COX side...at least my TV works.  Frustrating for you Apps/online guys with no sound or connections

KevinM2....I'm using Firefox, and do have problems with the login.  Cleared the cache, history here.  It sometimes works and other times fails.  I've used Chrome and Edge.  I'm able to login/off and re-login to these, so far.  With FF, I can't seem to pinpoint the problem...after enter of id/pass, the screen re-displays and I need to re-enter id/pass then I get a message.  I've been trying to play with different login paths to the watchTV for Cox... I see an Adobe Flash msg on the Chrome/Edge, but I believe that is after my ID verify.  With FF, I get the Whitelabel error from above.  I've also looked to see if there are any bloc of the idm.east.cox.net

Now about the original poster's, not getting sound on the TNT 18/1018 channel.  I get NO sound using all 3 browsers....there may be others, but TNT is a no sound for me.

Looks like I fixed my problem myself. I tried Cox help but was told to reset the cache and all sorts of stuff I had already done. It seems, for some reason, that Video Description was off. When I clicked it on, then sound! I just looked at it again and was going to take a screen shot to show and then it was off again. No sound. I clicked it on and then sound again. In the right lower hand corner there is a text bubble that is for Language Settings. This has something called Video Description.

At the screen bottom right there is a Language Setting icon that has 3 buttons that can be slid on/off.  the 2nd is Secondary Audio (SAP).

You can also toggle SAP by pressing "S" on the keyboard.

? - Display keyboard controls

C - Toggle closed captions

M - Mute audio

S -  Toggle SAP

V - Toggle video description

CurtB...Wow, look at this info, Awesome with all your great thoughts and insight.  You sure are into many of these hidden gems along with your technical contribution.  The ?, which opens the Keyboard Shortcuts could be invaluable to the Cell Apps guys....eliminates picking something on the screen.

Still no resolution to the Sound issue for watchtv or Apps from Cox.  Hope users with issues can find some hope to this dilemma.

Click "Player Settings" (wheel in lower right of screen).  Then click "Player Shortcuts" (box in upper right of the just opened pop up).  I tend to explore stuff to see what's available. 

I would try toggling Mute (M) On and Off for those channels with no sound.  It probably won't help, but you never know.

On both my mobile apps and desktop browsers i will get no sound on specific channels.

I tested https://watchtv.cox.com on my desktop using Chrome.  The video and sound worked for every channel I tested... CNN, TNT, Paramount, WGN.  I don't have the Contour app installed.  Is there anything about the app that could possibly affect an individual's account settings on a Cox server in a way that would alter performance when accessing the website with a desktop browser?

Also, just to eliminate possibilities, did you verify that neither the website's sound or your computer were muted when viewing channels with no sound?

CurtB, so it works for you, interesting.  I tried Chrome again this morning (usually use Firefox) but have also found the issue on Edge.  I'm on W10 machine here in SoCal.

For Chrome, TNT (18), Freedom(19), Paramount(52), WGN(68) plus newly found trvl(53), tlc(54) bravo(55) all did not work.  CBS(2) & weather(51) worked.  When channels failed, it was usually the sound.  On a few, the screen was blank, or the video was stuck.  After sliding the SAP to the right, the Sound did appear.  Sometimes I need to wait till the "Attempting to Resume" refresh screen to appear.  On a few, if SAP is not there, try the Video Description icon.

On the platforms, I had to Enable Adobe Flash.  Also, I do not have the App on my cell phone.  I do check my COX account for recent phone call history, account info, and this forum.

My email to COX said ticket CUI000008292144 was created.  Based on this forum comments, both the watchtv and cell phone App may be affected.  Not sure why your Chrome worked.....do you have Firefox or Edge.

It's normal for Adobe Flash to have to be enabled for Chrome.  I don't use Firefox or Edge.  While we may be accessing the same network channels with the same web browser, we're in different markets.  That's a Cox variable that may produce unpredicatble results.

I only have two minor issues with the https://watchtv.cox.com website.

 1) The "Controls Auto-Hide Delay" event doesn't fire when a new channel is selected.  It requires a cursor move or full screen change for screen controls to be removed.  It's a minor issue and the main reason it's annoying is because it would be such a relatively simple thing to fix.

2) When "X" is entered to exit a channel, the current channel isn't always the channel in the grid that's selected.  It complicates grid navigation using the keyboard.

I contacted Cox about both of these minor issues a long time ago.  As far as I know, there hasn't been an update to that site recently.  I don't expect a change before the update to replace Adobe Flash that is scheduled to be retired next year.

CurtB....yes, the watchtv is novel...I have never used it till the bug showed in this Forum and I wanted to peek at the issue.  It happens on all browsers, and apparently the cell Apps.  Your observation about the location of broadcast is interesting, because I don't see any other suspicious fault.  Cox has a ticket, but there is no online tracking available.

The "X" closing did bother me when I wanted to know where I was when I exited.  Maybe a tweak on Cox part could help. 

I think the problem has been resolved. I received an email from Cox Support and they told me they worked it out and indeed I have checked the problem channels and they are working. I have not checked every channel as that would not be very practical, but it seems that we are back in business.
