Some Comcast Basic Cable customers around the Bay Area have reported audio issues with KQED and KQED Plus, on channels 9 and 10. The problem is not related to KQED’s transmission but may be caused by the language setting on your Comcast remote control.
If your Comcast remote control is black, please check for a button labeled “Language” or “Lang” on your remote control. Instead of this button, your remote control may have a small white button near the bottom (possibly not labeled), between the “Volume” button on the lower left and the “Channel” button on the lower right. Press the “Language”, “Lang” or white button to determine if your language preference may have been reset to French or Spanish. If it has, press the button repeatedly until it is set back to English. This should restore your audio.
If the problem persists, or if your remote does not have either version of the button described above (ie., the Comcast silver remotes do not have this button), please contact Comcast for assistance with checking your language settings and/or turning off the SAP channel on your TV set.
