I find out that bluez a2dp also do not work fine in case of multiple
vendor codecs in remote. So I think bluez also needs this android bluez
patch.

Originally I consider to use check_vendor(profile/audio/a2dp.c)function
from avdtp_find_remote_sep. but it does not seem good to me.

Could you give us the guidance?

Thanks
