Sejak memperbarui ke ubuntu 14.04, setiap kali perangkat Bluetooth saya idle atau saya matikan lalu hidupkan kembali, itu default ke pengaturan Telephony dan saya tidak bisa mendapatkannya secara default ke a2dp.
Saya telah mencari dan hanya menemukan beberapa solusi yang mungkin seperti
pengeras suara Bluetooth: mode yang disukai "pemutaran High Fidelity" (A2DP) tidak disimpan
tetapi ini tidak bekerja untuk saya. Ketika saya menggunakan Disable=Headsetseperti yang disarankan dalam posting itu, itu berfungsi sementara tetapi setelah beberapa saat, jika perangkat saya terputus maka tidak akan terhubung kembali sebagai perangkat audio.
Saya menggunakan headphone Bose Soundlink dan /etc/bluetooth/audio.conffile saya adalah sebagai berikut:
# Configuration file for the audio service
# This section contains options which are not specific to any
# particular interface
[General]
# Switch to master role for incoming connections (defaults to true)
#Master=true
# If we want to disable support for specific services
# Defaults to supporting all implemented services
#Disable=Gateway,Source,Socket
# SCO routing. Either PCM or HCI (in which case audio is routed to/from ALSA)
# Defaults to HCI
#SCORouting=PCM
# Automatically connect both A2DP and HFP/HSP profiles for incoming
# connections. Some headsets that support both profiles will only connect the
# other one automatically so the default setting of true is usually a good
# idea.
AutoConnect=true
# Headset interface specific options (i.e. options which affect how the audio
# service interacts with remote headset devices)
[Headset]
# Set to true to support HFP, false means only HSP is supported
# Defaults to true
HFP=false
HSP=false
# Maximum number of connected HSP/HFP devices per adapter. Defaults to 1
MaxConnected=0
# Set to true to enable use of fast connectable mode (faster page scanning)
# for HFP when incoming call starts. Default settings are restored after
# call is answered or rejected. Page scan interval is much shorter and page
# scan type changed to interlaced. Such allows faster connection initiated
# by a headset.
FastConnectable=false
# Just an example of potential config options for the other interfaces
#[A2DP]
#SBCSources=1
#MPEG12Sources=0
