Check your audio cables are plugged into the correct inputs. They must match (Input 1 , Input2, etc). you can also check the cables to see if they are good. Use an OHM meter. You can buy a cheap one at radio shack. Or even better - buy another set of audio cables.

No sound out of the pioneer vsx-1121-k

Try removing all the speaker and the HDMI connections; then use a headphone to listen to music from the tuner or a CD in stereo mode. Better in direct mode. If you hear your music correctly the receiver could be working correctly. If no music is heard, you may need to have it repaired professionally.
If you can hear music, connect the main FL & FR speakers and verify you can hear music that way, without the headphone connected.
If you can hear music that way, connect the center and rears. Try a mode that uses all channels to verify all sound channels are working.
Then, and only then start adding your HDMI connections.
Good luck

Radio sound low and squeeky, works good in summertime

The volume control on your radio is called a potentiometer, which may be going bad. It works better when its warm because materials expand as they warm up and make tighter contact with each other.

It is also a possible a bad wiring connection exists. Poor contact will cause static, poor audio quality and intermittent output.

Your radio will have plug type connector(s) Your speakers will most likely each have two wires with single female spade connectors of different widths (keeps the polarity correct) the wire with the stripe (of whatever color) will be connected to the negative (-) speaker terminal.

So you need to check all the connections, one is making poor contact.
If both speakers (assuming you have two) sound good or bad... then start with the plug connectors for the radio and any independent black ground wire coming out of the radio.

If one speakers sounds okay check the connections on the other one. You check the connections by carefully pulling the speaker wire off of the speaker and then carefully pushing it back on making sure it feels tight and secure.

PS: If you pull the fuse for the radio, the radio will have no power and will not work. The radio coming on proves the fuse is good.

PSS: Your owners manual should provide lots of information on your sound system components.

Panasonic pt47x54j service manual

Checked the usual things:

Speakers not switched off in menu for TV (or a box if used)

Volume on set or a box not all the way down?

Sound out in just one speaker--this model the wires from the speakers are fairly tight--they can come undone where connect to the speaker(remove front grill below screen and examine them)

There is no fuse per say for the speakers or audio circuit.

Yaris radio - sound stopped coming from speakers

I had the exact same issue with my 2007 Yaris. I took the radio out and checked all the connections- (all Good) then traced the wires through out untill I reached the trunk. I had a bunch of stuff in the trunk that had some how hit the speaker connections and bent the connections on one of the speakers. I removed all the stuff from the trunk and re-solder the connections. After that the speakers kicked back on for the entire car.
Check the trunk - if you have it loaded with junk like I did, this may be the cause of your speaker failure.
Good Luck!

Some high-power players have an internal fuse in line with the speakers so that an external short will not blow the output transistors. Have someone skilled look for this.

Also, check that your speakers are not wired backwards; some speakers will connect one side of the voice coil to ground. If you connect the hot side of your CD player to the ground side of the speaker, you kill the sound.
