I suspect you'll find it's not working on other devices, either.Įdited by britechguy, 12 December 2015 - 01:15 PM. W59 ETR AM/FM stereo with auto-reverse cassette, graphic equalizer, clock, seek up/down, remote CD pre-wiring and six speakers, in convertible (100 credit). Provided there is any output to the speakers from the device (that is, it can't be muted or else there's no signal to adjust) your speaker volume knob should be able to boost or reduce the volume there. You can test out whether my theory is correct by plugging these speakers into something like the output jack on your smartphone and play music from there.

Sometimes it's that the rheostat has become dirty over the years. My only quick recommendation would be to remove whatever cover (probably on the bottom of the speaker) you can that gives you access to the "innards" of the volume control and give them a quick spritz of either TV Tuner Cleaner (yes, you can still buy this at places like Radio Shack) or a deoxidizing spray like Caig DeOxIt or similar. These volume control knobs on the speakers work entirely independently of any device driver and are an analog adjustment just like every speaker control knob you've ever used (or at least all the ones I've had experience with are). It sounds to me like your volume control rheostat in the speakers themselves may have finally bitten the dust.
