iOS 18 and Airplay issues with volume changing

When I updated to iOS 18 on my iPad Air 2024, and I stream to my streamer via Airplay, two issues have occurred consistently. One, the volume on each song changes and I constantly need to adjust the volume on my stereo. Second, a few songs will play and at times when the next song plays there is no volume even though the song is playing, and I need to hit the double arrow back button to go bak to the beginning of the song and the song will play and output sound. Neither of these two issues occurred until I updated to 18. Any others experiencing the same issues?
