When playing with JBL charge 2 speaker, I found that the music stutters badly whenever I start scanning, and it goes back to normal after the scanning finishes. I am wondering if this is a bug in Bluez, so I tried another speaker, Beats Pill, but it turns out that Pill plays smoothly even if I start scanning. Speakers: - JBL charge 2 (A2DP/HSP/HFP) - Beats Pill (A2DP/HSP) Since I only use the speakers for audio output, A2DP profile was used. Somehow L2CAP socket buffer has no space for the outgoing audio data during scanning, so I keep getting EAGAIN error. My guess is that the previous frames have been accumulated but never been consumed, but who is blocking ACL for sending audio data? Does anyone see this issue before?
