sound cutting out

[kickass audio]

Update on my problems for now. I was able to get the radio updated to the Y175 firmware everyone has been reporting as the fix for the bluetooth call audio crackling and only have 1 issue now. The issue I have is that pressing and releasing the voice prompt button on the steering wheel does nothing but you can still use "hey google" or "OK google" to issue commands (pending you have onstar data service active or are connected to WiFi with the truck).

 

The dealer couldn't update my original radio to Y175 firmware and said it's been something they run into a lot lately where the radio module is just defective and needs to be swapped out (radio's cost over $600 from what I found).

 

The dealer was also nice enough to get me a loaner 2025 silverado LT. albeit it had the turdomax engine that sounded pathetic when started. it also had a issue where the turn signal stalk would not turn itself off after completing a turn and i'm putting my money on it being that it has a column shifter and it moved the entire steering wheel cover when you put the truck into gear. I hope nobody else with a shifter in their dash runs into that problem.

 

The dealership replaced my radio module (part #: 85086705) and reflashed the new radio with the latest update (build number: full_gminfo37_gb-user 12 W213E-Y175.5.2-SIHM22B-383.1 213 release-keys).

 

I provided them with preliminary bulletin ID's PIT6241 (relating to the crackling noise when on a call) and PIT6101M (relating to the short loss of audio output during a drive cycle).

 

The dealers service write up details document #'s 6557575 and 6730784 which i'm not sure the details of but I would imagine it's for the same problems of audio drop out and bluetooth call audio crackling.

 

The effects of the Y175 update are:

 

1.) As my truck experienced with the Y172 patch that was installed as part of the recall late last year, navigation audio was set to 0 along with the google assistant voice prompts. This is an easy fix and I just tell it to read aloud a text message and continue to raise the volume up on the radio to my desired level while it's reading the google assistant prompt. I also set a destination on google maps and when I know it's giving commands for where to turn, etc. just turn up the radio volume to the desired level.

 

2.) The microphone button on the steering wheel doesn't interface with the radio anymore. It only will claim to send the command to my phone as controlling the assistant feature. If you are paying for onstar data services or have a connection to your truck via WiFi and mobile hotspot, you can still use "hey google" or "OK google" to give commands like send a text message, set the cabin temperature, call someone, etc.

 

3.) The radio operates the fastest I have ever experienced. I am able to switch screens and see notifications that I never had before like when an app is updating through the play store, different setting screens for items that need attention. 

 

4.) Some quick testing shows that only 1 time out of the 20 messages I received with RCS chat enabled on my phone were now coming through the radio and able to be read aloud to me. I was never able to get RCS chat messages to play through the radio in a consistent manner unless I turned off RCS messaging on my phone as a whole.

 

5.) I still have a brief 1 second outage of sound at rare times but the audio comes right back on and i'm not concerned about that. It ONLY happened when I was connected via WiFi and also occurred in the loaner truck so it just seems to be another GM bug that needs to be worked out eventually.

 

6.) Unrelated to the update but as part of the radio replacement, I now have a new XM radio ID and needed to re-enter the subscription to get it activated. It did come with a trial probably for a week is my guess since it was a new radio. I also had to setup my offline maps again and have them download to memory along with pairing my phone and WiFi back up. Nothing that is too hard for the average person to handle.

  this best describes my issue, but when this happens it won't reset unless I shut the truck off. At the same time out cuts out, my channel selector on the back side of the steering wheel on the left side fails to work at the same time. It also resets when the radio does. So, they are definitely are related.

I have heard of others where the audio never comes back but not anyone mention the issue with the channel selector buttons stopping.

 

I suspect it's a radio failure for your truck. Did you try to boot into safe mode and see if you can drive around in safe mode and see if your problem occurs then too?

They did some updates to the radio and couple of times. Then replaced the radio module, still same issue.

Ive had the same issues on my 2024 GMC Sierra 1500 it was fine for the first 6 months and then it began sometimes its just short cut outs on any source XM/Apple/FM makes no difference and sometimes it will drop out for a long period now im at the at the point where if im on the highway and no ones behind me i put the truck in neutral shut it off ... touch the brake and restart it and then throw it back in drive and carry on. Sometimes this fixes if for long enough to enjoy the drive. Ive made videos while driving and changing sources to show GM what is happening. My stereo shop checked everything they worked on during the amp/sub install and they said there are no voltage drops or any loose connections that they could find and its a head unit issue. So a couple months later and this sound cutting is absolutely Temperature and voltage sensitive.. to the point when its below 0 out it will cut out and as it warms and gets above 0 there are no cuts in the sound.. Im lost as to this but GM refuses to diagnose the issue unless i Have the aftermarket speakers and amp taken out and put back to stock.. seems absurd and i figure ill have the truck for one more season and then its gone before it gets cold anyways so issue fixed far as im concerned.

The dealership I went to several times regardingthis has pretty much brushed me off over this. It's very frustrating on it's own, let alone while very important calls with my neurologist, back surgeon, work and so on...
