Hi, I recently noticed that there is no longer any sound coming from my TV. It is an Element TV, model elefw408 connected to the cable box (wireless receiver, AT&T) with an HDMI cable. It used to work fine.

I have not used this TV for about half a year, last time I used it changing the volume would bring up a circle in top right of the screen with volume indication (if I remember correctly it increased in 10 point increments), now the onscreen indicator for changed volume is a linear bar at center bottom that has increments of 1. No idea if this could be relevant. My primary TV gets sound just fine, so I doubt our recent switch from coax to fiber is the culprit.

I read a couple posts here for suggestions, here's the ones I've tried:
Inserted headphones to TV to check if it was the speakers, no sound in headphones either (completely silent, no static)
Connected an optical cable from cable box to TV.
Restarted receiver.
Unplugged TV + receiver for a few minutes, unplugged and reinserted HDMI cable on both ends while TV + receiver was off.
Tried all three HDMI slots.
Turn TV on before receiver and vice versa.

One suggestion I have seen is to manually change audio output in the menus, but I have not been able to do so as there doesn't seem to be any options for that in the TVs menus, or the AT&T menu for the receiver.

Any help resolving this would be very appreciated. Thank you.

It seems strange that the volume indicator is different now. I suspect that one was generated by the cable box and the other by the TV.
If the cable box is set to variable audio and it's turned all the way down the TV volume control won't have any affect.
Also check the cable box audio menu. There may be a setting that you need to change. Sometimes the audio is routed to the optical audio out and turned off in HDMI.
Last connect a different source to the TV to determine if the TV is the problem rather than the cable box.

You were right about the cable box having a separate volume control, and that that one was turned all the way down. My problem was that there were no volume buttons on the cable box, nor did the cable box menus provide any way to adjust the volume (my cable box is a cisco isb7005). If anyone runs into the same problem, here's what I had to do to adjust the volume:
Press and hold the at&t button on the remote, press ok and release both then type in the number 955 followed by enter. This made it so that pressing the at&t button followed by volume altered the cable box volume, and TV button followed by volume changed the TV volume.
