Handler for absolute volume requests from a remote peer. See AVRCP v 1.6.2 section 6.13.2.
Absolute volume is represented as a percentage using one byte with the most significant bit
reserved. 0% is represented as 0x0 and 100% as 0x7f. Volume should scaled between the
two values.
Set get_all if we want all attributes of a media element item.
Set attribute_list if we want to get only the specified attributes.
If get_all is set to false, it will be treated as attribute request
with emtpy list of attribute IDs.
