Twice now, the audio in the truck has quit.  No radio, can't hear my phone call and even cannot hear the blinker.  Turning the truck off does not help. But works the next day or next time that I get into the truck.  Not sure how long it takes.

Press and hold the call hang up button on the steering wheel for about 15-20 seconds.  That will hard reboot the radio.

 

If it keeps doing it, take it in.  There is likely an update that might fix it.

I had the same lack of audio this year on my 2020. I drove it to the dealer, they verified, checked for codes and there was none. They gave me an appointment for a few days later. 

I shut it off and restarted with the same lack of audio. It sat overnight and the next day everything worked fine and continues to work fine months later. 

I'm sure someone on here has the answer to this.

Would that also fix not hearing the clicking of the blinker?

 

 

Turn signal chime is run via the radio.  Has been for almost 30 years on GM vehicles.

I did this to mine. It fixed it.

My loaner had that happen (no sound from anything) last week. "Fixed" itself an hour after shutting it off and then restarting. A 2026 Sierra 1500. Hasn't happened since.

I had this happen several times on my truck.  Tried the reset/reboot with the steering wheel button and still lost audio and turn signal sound.  Took the truck into the dealer, they did a software update on the radio and now it has worked ever since.  Also built in Google Maps would shut down several times on a 1 hour trip, since the software update Google Maps has worked good as well.

Have you been avoiding the "over the air" updates?   I had 3 or 4 in the last 3 months on my 2024, 2 in one day recently.  Don't know what they accomplished.   I had the no sound from radio once last year and they rebooted system, took about 15 min. Did not even need a tech, service advisor did it.  Lots of these gremlins with the software driven vehicles. The Sun goes behind a cloud and a computer glitch surfaces.

In my 21 Silverado or now my 25, I never ever have had an over the air update come through, and I do manually go into the radio and check for the updates, maybe once a month or so.  For the no radio volume and turn signal noise, they told me they had to use the scan tool and preform the update, which took several hours.  For the Google Maps update, the service advisor did that one outside in the parking lot, which did take quite a while as I am an Iphone user so I had to download the Google email app, create an account, and then go through with the updates by logging into my radio.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
