Would be interested to = hear whether that does "the right thing" with your APU or on other's = devices? The key variable is TARGET_BURST_DUR_MS in defaults.sh. Let me = know how this performs for you (or whether there are bugs). As Toke = proposed elsewhere I will try to streamline that branch to only = configure burst size by duration so expect some changes in organization, = but it should keep functional.
