XPR3500 sound problem

[VA3ADP]

So yesterday, I had some changes to make on CPS to my XPR3500. I read the radio and when I turned it on, the volume was very loud as if it was turned all the way up, yet I had it at a quarter of the way up. So I tried adjusting it with volume knob and still nothing.

One thing that we totally strange was the volume bars on the screen (when the volume was in its muted position) was still showing one bar even though the knob was well below in its muted position like I just mentioned.

Any ideas on how I should proceed? Sounds to me like a software issue?

Thanks!

sounds like a bad Volume control knob

No changes were made to the radio beforehand correct?

Sorry let me rephrase my original post, I had made some slight changes to the radio. Added some private call Id's which I wrote to the radio.

But nothing audio wise that you know of?

Well I can't turn the volume down. It won't even show the mute icon on screen, just the one volume bar will appear. The volume is at full blast.

You are not answering the questions asked........................ Did you change ANY audio settings? If so, you need to revisit those changes. Look under your audio settings and make sure you did not specify a Minimum volume level. Also, make sure you do not have Intelligent Audio turned on. There are other possibilities, but do not want to proceed without further info. TT

Well that was the other thing I did. I was re programming the radio to turn intelligent audio off as well and Ananlog AGC. I will look and see at minimum volumes if I had accendelty touched something

Load back in the version of the programming before you made the changes. If it fixes the volume problem then you know it is something with the programming. Hopefully you saved that version before you made your alterations to the code plug.

Too late for that lol I saved the codeplug after I wrote the radio then I accendelty deleted it

The analog AGC has nothing to do with it. It just means that whenever you key up the radio will automatically adjust your gain based on the amount of background noise.

In the radio in the menu there is an audio profile. I forget the exact name, & is accessible from the front buttons. Turn off loud. That should work.

I believe your referring to audio profiles. I believe I had mine set a default. I will double check when I get home.

So I tried adjusting the minimum fixed volume in CPS which i then wrote to the radio. Still no luck the volume is still stick at max? Could this be a software related issue?

If anything it's likely a hardware issue. If you never had this problem before and experienced it suddenly then I would contact Motorola to see if they know what's going on and if it is a hardware issue have them fix it.

So just to do a little bit of follow up on this issue for anyone experiencing the same issue. Discovered that this is known issue on the 3500. So I wrote the latest firmware upgrade to the 3500 (R 2.8.5) and still nothing. So I went out on a hunch and recovered the radio to R 2.8.5 and SUCCESS! Volume was all back to normal.

On the downside, I had to reprogram my whole radio which took a while to complete, but eventually got it done. I do really appreciate the ideas of everyone who contributed to the thread, but I do have one burning question that I noticed after the reprogramming was complete. (probably should start a new thread on this since this is an unrelated issue)

When I unkey on digital, I notice there is no more little click noise when I unkey with my RSM I found this weird because I always have heard it on digital with the previous updates as well as it seems to work fine on the PTT on the radio. I went into the mic follow options on CPS and selected it to follow the accessory mic/speaker when attached.

I have always had that box checked and of course it has no affect on the mic unkeying. I am slowly beginning to think its maybe a software glitch in this latest version. I referred to the release notes and so far nothing has been mentioned? I might give Motorola a call tomorrow and see if they know anything about this.

Any ideas on what could be the issue?

Thanks

Can't say I have ever heard that one before...
