+x Tony N - 8/26/2021 7:57:14 AMThis may or may not help you...I run SD on my Android smartphone and have a wired connection from the phone's audio connector to my Trig radio's Ext Audio In.I usually fly with a pair of Clarity Aloft in-ear headsets for myself and wife and the SD audio warnings are of good volume.Yesterday I took a friend flying and used a pair of "traditional" headsets and found the SD audio warnings very low level and just usable.So, your audio level issue may be due to the headset you are using. Hope this helps....
