No audio Everything works on my DAV S300 but for one thing. There is absolutely no sound to the speakers not even the test tone. All of the front panel indicators are ok and the disc tray works fine. It just acts like it is on mute but it is not. Failed after not being used for three months while we were away.I do hear the audio at the phono jacks. I took the cover off and all of the fuses look ok and there is no visible indication.

Same exact problem. No clue what the solution is, though. Same exact problem. No clue what the solution is, though.

Another guest - and I also have this same problem. I can get the audio working through the TV, but the surround speakers I get nothing (not even the test tone). ANY IDEA'S WOULD BE APPRECIATED.

on my system the sound field just shows phones and there is no sound through the speakers.When phones inserted in to jack I do get sound but only in the phones. The player wont let me change sound fields just stuck on the 2 phones options.
I only get sound through the tv.
Any ideas folks ?

Sony DAV-S300 !!! Sound Problem !!! Same Problem like by Willly
..., ...Polkared ...etc The Box working COMPLETELY(Display,DVD,AUX's,TUNER,SETTINGS -Sound Field ,HEAD-PHONE) OK!!

BUT !!! just the sound switch OFF and ON,sometimes. and when is no
sound then the SOUND CHECK is not working too ( Normal) Now my box is
in pieces, and I try to find out where is the Problem. Its seems to be
a protection ( I don't know - OVERHEAT , OVERLOAD ... ) If somebody
want the SM just write a Comment

Sounds like willy's problem is exactly the same as mine. Works at the headphone socket, but no sound otherwise (though haven't tried the phono out on the back)

Another thing I have noticed is that it no longer makes the noise that sounds like a relay click when switching on.

I have checked all the speaker connections, MUTING is not on, and the test tone can not be heard. The loss of sound affects all functions (DVD, CD, tuner). It's as if the surround sound amp is not being powered up.

I have opened up the box and checked continuity through any internal fuses - all seem fine. Didn't see anything suspicious in there.

No audio on my DVD S300 out of the speakers. The dvd players works ok but no audio, only using the RCA outputs. No audio on my DVD S300 out of the speakers. The dvd players works ok but no audio, only using the RCA outputs.
