Yes we need input section as well, this was just example, the complete
sections would look like (copied from real device):
...
hsp {
outputs {
hsp {
sampling_rates 44100
channel_masks AUDIO_CHANNEL_OUT_STEREO
formats AUDIO_FORMAT_PCM_16_BIT
devices AUDIO_DEVICE_OUT_ALL_SCO
}
}
inputs {
hsp {
sampling_rates 44100
channel_masks AUDIO_CHANNEL_IN_MONO
formats AUDIO_FORMAT_PCM_16_BIT
devices AUDIO_DEVICE_IN_BLUETOOTH_SCO_HEADSET
}
}
}
...

This looks like default configuration for Intel devices.
