I've reviewed that as well.
I think I'll make a test release so we can see what works and what doesn't.
Isn't there a bluez-alsa command that shows which codec is being used?
@jenzd may well know a better command. Here's one I gleaned from the bluez-alsa issues long ago which queries the dbus
gdbus call --system -d org.bluealsa -o /org/bluealsa -m org.bluealsa.Manager1.GetPCMs
So, for example, with a stock moOde player paired and connected to a JBL Flip2 BT speaker, I get
Code:
pi@moode:~ $ gdbus call --system -d org.bluealsa -o /org/bluealsa -m org.bluealsa.Manager1.GetPCMs
({objectpath '/org/bluealsa/hci0/dev_00_1D_DF_AA_27_37/a2dpsrc/sink': {'Device': <objectpath '/org/bluez/hci0/dev_00_1D_DF_AA_27_37'>, 'Transport': <'A2DP-source'>, 'Mode': <'sink'>, 'Format': <uint16 33296>, 'Channels': <byte 0x02>, 'Sampling': <uint32 48000>, 'Codec': <'SBC'>, 'Delay': <uint16 150>, 'SoftVolume': <true>, 'Volume': <uint16 32639>}},)whereas, with the same player connected as BT speaker for my iPad
Code:
pi@moode:~ $ gdbus call --system -d org.bluealsa -o /org/bluealsa -m org.bluealsa.Manager1.GetPCMs
({objectpath '/org/bluealsa/hci0/dev_D0_D2_B0_DB_13_78/a2dpsnk/source': {'Device': <objectpath '/org/bluez/hci0/dev_D0_D2_B0_DB_13_78'>, 'Transport': <'A2DP-sink'>, 'Mode': <'source'>, 'Format': <uint16 33296>, 'Channels': <byte 0x02>, 'Sampling': <uint32 44100>, 'Codec': <'SBC'>, 'Delay': <uint16 150>, 'SoftVolume': <true>, 'Volume': <uint16 1799>}},)In both cases here the SBC codec is being used.
As Jens said, bluealsa --help tells us which codecs are available and in this stock moOde player they are just
Code:
pi@moode:~ $ bluealsa --help
Available BT profiles:
- a2dp-source Advanced Audio Source (LDAC, SBC)
- a2dp-sink Advanced Audio Sink (SBC)
...Since this is stock moOde, bluealsa-cli isn't present.
