My 996XT does not behave like yours is doing. Mine outputs the audio from the remote jack and never cuts out. That is what that jack was made for plus as you know, you can deselect some channels if you don't want to hear them out the remote jack.
I myself would not use the speaker output for feeding the line in. The levels and impedance are way off for one and you do run the risk of burning something open at the input jack on the stereo.
It would be better to build a breakout box so you can still hear the scanner audio at the scanner and then use a resistor for another jack to at least limit the audio that can hit your stereo if you cannot fix the rec out jack first.
I'd try and fix the record out problem first though as that is by far the proper way to extract audio to an external amplifier. It is fixed level also unlike the external speaker jack.
If you can't figure out the remote jack problem, then use the headphone out instead if the external speaker out. The headphone out is at least limited so you have less chance of frying something in the stereo.
I've used my record out jack on my 996T and XT for years to feed an external amp in another room and never had a singe problem with it.
Not sure why davidmc36 said you should not use the rec out jack as that is really its intended purpose, to feed line level inputs!
You already know you must select rec out for each channel or as a group so it should work fine. I know there are mutiple places that you can enable/disable the rec out jack so I'd double check them in your programming and then dump the programming back into the 996 maybe even after doing a reset to defaults.
My 996 has developed a new problem where the control channel data output setting is not sticking. I enable it and then later after I've turned the 996 off and back on, the control channel output is back to disabled.
Not sure what is causing this as it has always remained enabled in the past. I noticed it started doing this after I installed the latest firmware but not certain that is the real cause. I do plan on reverting back to the prior firmware and checking though when I have time.
Do you have some type of priority activated that could be interrupting the rec out audio? I've never seen that but maybe it is a bug that has never been reported before. Or maybe something with the latest firmware changed something. Try resending your programming after you make sure all your rec out settings are turned on. I'd even reset to defaults first and then dump your programming back into the 996.
I have seen some modern day amps and stereos that will shut down inputs if no signal is detected for a short time. They actually shut down the main amp section to conserve power like most modern TV's turn themselves off if there is no video signal after 15 or 30 seconds. Is it possible that is what is going on?
The REC out jack does not put out much of a signal so an external amp may think there is no signal but it should be plenty unless there is a long pause with no audio. Does your stereo have any power saving features that may be shutting the amp section down if it does not detect a signal?
Turn that feature off if possible.
Has this same setup worked in the past and have you changed anything if it did work in the past? I know the 996 outputs audio just fine out the rec out jack as long as it is enabled for everything. It can be enabled per channel for use when scanning plus it can be enabled for during searches and even enabled for the weather functions. I don't think there are any settings where the rec out cannot be activated really.
That's always been one of my gripes with the GRE models like the PSR-600, no line out or rec out. I had to search and add my own line out on a PSR 600. All radios should have a fixed line level output. And the way Uniden did it is even better as it lets you select what you want to come out of that jack.
If you cannot make it (rec out jack) work then do use the headphone output instead of the external speaker out. Much less chance of blowing something at the line in circuit in the stereo as the headphone jack output is limited in power mainly. It also uses a slightly higher impedance but not by much so you may still get distorted sound. I think the headphone out is looking for a 32 ohm load while the speaker out is looking for 4 or 8 ohms.
The rec out should be at 10,000 ohms.
A 2 watt audio signal from the ext speaker jack into a line in jack with as little as 1/4 watt resistors in your amps input is asking for problems along with distorted audio from the impedance mismatch. I would not risk it if it is an expensive amp.
