PulseaudioはA2DPおよびHFP接続用のシンクとソースを設定します。

PulseaudioはA2DPおよびHFP接続用のシンクとソースを設定します。

組み込みボードにA2DP + HFPプロファイルを設定しようとしています。目標は、電話に接続するためにpulseaudio 12.2、ofono 1.18、bluez 5.41を使用し、必要に応じて自動的にA2DP、HFPプロファイルを使用することです。バージョンを更新してデーモンを構成するために本当にたくさんのことをしました。これで、接続後に利用可能なHFPプロファイルが表示されます。

A2DPは完全に機能し、携帯電話から組み込みボードに音楽をストリーミングできます。電話が来たらBluetooth経由で応答できますが、通話中にHFPがアクティブなプロファイルのようです。奇妙なことに、HDMIディスプレイが接続されている内蔵ボードにオーディオはありません。

下からその様子をお見せします。 A2DP経由で携帯電話から音楽をストリーミングすると、次のソースとシンクが表示されます。

HFPを使用して電話をかけるたびに、次のソースとシンクを受け取ります。

通話中は、受信機がHDMIモニターからBluetoothデバイス自体に変更されるため、これは奇妙です。以下で私のものを見つけてください/etc/pulse/default.pa

.fail

### Automatically restore the volume of streams and devices

#load-module module-null-sink
#load-module module-pipe-sink

### Automatically load driver modules depending on the hardware available

#load-module module-null-sink sink_name=rtp format=s16be channels=2 rate=44100 sink_properties="device.description='RTP Multicast Sink'"
#load-module module-rtp-send source=rtp.monitor


### Load additional modules from GConf settings. This can be configured with the paprefs tool.
### Please keep in mind that the modules configured by paprefs might conflict with manually
### loaded modules.
.ifexists module-gconf.so
.nofail
load-module module-gconf
.fail
.endif

### Automatically restore the default sink/source when changed by the user
### during runtime
### NOTE: This should be loaded as early as possible so that subsequent modules
### that look up the default sink/source get the right value
load-module module-default-device-restore

### Automatically move streams to the default sink if the sink they are
### connected to dies, similar for sources
load-module module-rescue-streams

### Make sure we always have a sink around, even if it is a null sink.
load-module module-always-sink

### Honour intended role device property
load-module module-intended-roles

### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle

### If autoexit on idle is enabled we want to make sure we only quit
### when no local session needs us anymore.

### Enable positioned event sounds
load-module module-position-event-sounds

### Cork music/video streams when a phone stream is active
load-module module-role-cork

### Modules to allow autoloading of filters (such as echo cancellation)
### on demand. module-filter-heuristics tries to determine what filters
### make sense, and module-filter-apply does the heavy-lifting of
### loading modules and rerouting streams.
load-module module-filter-heuristics
load-module module-filter-apply

load-module module-switch-on-connect

### Make some devices default
# Make HDMI default
set-default-sink 0
#set-default-source input

私のALSA設定は次のとおりです.asoundrc(デフォルトはHDMIデバイス)。

pcm.!default {
    type hw
    card 1
    device 0
}
