+Subject: [PATCH 6/6] Add option to change eSCO Transport Unit Size
+
+Fixes Bluetooth calls on some Samsung devices if set to 16.
+
+It's still unknown if other Treble devices need other values so it's preferred to leave this able to be configured with another integer.
+
+This applies to mSBC T2, T1 and CVSD codecs
