I am running the latest before on the 2007 XL (no WAAS)

But no clue on how to save the changes.
Yeah, that's where I remember it from the previous releases. But no luck on the latest version - my COM page under GIA has only 4 settings: "FREQUENCY", "SPACING", "VOLUME" and "EMERGENCY VOL". No more "SIDETONE VOL" setting. :scratch:

If you change a value, I think you just press the ENT button and it writes the "set" value to the "active" value (by updating the GIA settings). On some screens, there is a button at the bottom like "SET>ACTV" which writes the new settings to the active device, but I think the COM screen just updates when you press the ENT key.

I tried that the first time but it didn't save the settings (you will notice that when you switch from COM1 to COM2 on the settings screen as one needs to make the change to both) and I had to explicitly save the configuration. Let me go back to the aircraft and reproduce and then describe the steps.

Re software version: I have 0321.22 as the aircraft does not have WAAS. Interesting to hear that the configuration parameter was removed in 0321.23, I wonder whether it was merged with another one?

Yes - I have the Non WAAS 2007 - i can see the store button on the bottom of the page but it is gray out - even when I am changing the setting of the sidetone - no luck yet.

Re: PTT microphone volume

Almost a year later I think I managed to get to a solution the sidetone volume issue: Although the sidetone volume can be set on the G1000 system maintenance configuration page for version 321.22, it indeed does not save the sidetone volume setting and does not really help with resolving the issue. I had changed the volume of my headphones when I last described the sidetone volume solution so it was not a valid test under the "leave everything else the same" test conditions.

What I have found to help and resolve my sidetone volume issue during my last flight is to follow the audio panel preflight procedure listed in the G1000 pilot's guide (see attachment):

I previously always had my Bose A20 headphones always set to the minimum volume and regulated COM volume through the COM volume knob, however it had the side effect of NOT increasing the sidetone volume. As a result, the sidetone volume was always too low.

This time, I followed the preflight procedure which starts with the headphone volume control set to maximum (instead of my minimum setting). As a result I was forced to reduce the intercom and COM radio volumes, which had the desired effect of increasing the sidetone volume to a good audible level on a relative basis.

This might explain why some forum users reported no issue with the sidetone volume whereas others did.

For those who did report an issue with sidetone volume that was too low, could you try following the steps listed in the preflight procedure to see whether that fixes your issue as well?

I was going to start a new thread for my question, but it seems pretty plausible that it's actually related to this thread.

My issue is with using the Sirius XM radio while flying. The Sirius programming seems to come in at about half the volume of the comms radio and the passenger/pilot intercom. Even turned up all the way, it's so faint that it's not really worthwhile to try to listen to it. I can usually (sorta, kinda) figure out what the tune is, and that's about it. If you want to hear lyrics, forget it.

It's not a headset issue, because I've replicated it out of both sets of front seat jacks with both Zulu.2 and DC headsets. Same thing no matter what. Any suggestions? Because if I can't get the volume up, there's no point in paying extra for the XM radio programming.

Sara, I'm guessing it's just a com/headset setup problem. If you have your com radios volumes set high, then the headset volume will be set low to make it sound right. Conversely, if you set the com radio volumes to a middle level, like 40% or 50%, then the headset volume will need to be turned up, and with that, the xm volume gets turned up. The downside for me with very high headset volumes (very low com volumes) is that I hear transponder interference.

I've tried the obvious stuff, thanks anyway. I spent several hours during a multi-day cross-the-US flight (lots of time with empty hands, the AP flying the plane, and dead air to listen to) playing with every level (and combination of levels) on the radios and the headset, and with the obvious stuff on the G1000 XM page. No joy.

So now I'm looking for non-obvious answers. A few people have suggested that this is just How It's Supposed To Be, but I'm not ready to buy that yet.

Your shop may be able to adjust the levels on the GMA 1347 configuration page. It's been a long time since I looked at it, but I think the LEVELS page may have a setting or two for aux/music inputs.

That is definitely not how it supposed to be. Mine can get very loud.

We had exactly the same issue back when we owned a DA40 -- we couldn't hear the music (especially classical) even with good noise-cancelling headsets. The solution (as suggested by Chris) is to boot the G1000 into Maintenance Mode, and then change the default value for the GDL69A music input to a higher volume level.

I've successfully done this on both my DA40 and DA42.
