2/5/24, having this same problem (no audio on MSNBC). This has been happening off and on for quite a while. First time I spoke with tech, they rebooted my cable box from the help line - MSNBC audio started again, but after a couple days, it was gone. Next time, tried resetting from home (pulled power cable for 30 seconds), did not fix. Took the cable box in and swapped it for a new one, same thing is happening again today. Checked the SAP setting, appears to be turned to English. Have checked other channels, they seem to be fine, for us it's just MSNBC. Resetting cable boxes is NOT the solution, at least from home. If somebody told me some right wing nutjob who works at Cox is doing this to MSNBC, I would believe them...
