Problem seems to be that we need to set the transport state to playing since we introduce the following code: if (cp->available == PA_AVAILABLE_NO && u->support_a2dp_codec_switch && pa_bluetooth_profile_is_a2dp(profile)) cp->available = PA_AVAILABLE_UNKNOWN; That means every A2DP profile will be set to unknown including even if they have no transport yet, so now we have to set the initial transport to playing which hopefully it is just a matter doing the following changes (not tested): diff --git a/src/modules/bluetooth/bluez5-util.c b/src/modules/bluetooth/bluez5-util.c index 4e4ab0cb8..429914328 100644 --- a/src/modules/bluetooth/bluez5-util.c +++ b/src/modules/bluetooth/bluez5-util.c @@ -1837,6 +1837,7 @@ static DBusMessage *endpoint_set_configuration(DBusConnection *conn, DBusMessage t->acquire = bluez5_transport_acquire_cb; t->release = bluez5_transport_release_cb; pa_bluetooth_transport_put(t); + pa_bluetooth_transport_set_state(t, PA_BLUETOOTH_TRANSPORT_STATE_PLAYING); pa_log_debug("Transport %s available for profile %s", t->path, pa_bluetooth_profile_to_string(t->profile)); -- Luiz Augusto von Dentz _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
