My 2021 3.0 Sierra with the 8" premium infotainment system has issues with the audio cutting out at random.   It doesn't matter what the source is (Alexa, FM, AM, USB) including taking a call via Android Auto if the audio is cutting out it will disappear from all sources.  Went in for my first oil change and they flashed my Infotainment system to V158.3.2 hoping to fix the issue.  I would say it's less frequent but still happens quite often.  Does anyone else have this issue that was actually resolved?  Also, does anyone have a version newer than V158.3.2 or is this the current release?
