![]() Would I have to fork the bluealsa-aplay process with & in the script also? It doesn't change the output of the script at this time.Īnother issue I get randomly when running bluealsa-aplay is bluealsa: Transport not available: /org/bluez/hci0/dev_(my device mac address)/fd1īut if I execute the command right after startup, it is fine. I run the script with root permissions, and all the commands are the same as I would do manually. So I tried to put them in a shell script, but the script always says bluealsa-aplay: BlueALSA connection failed: No such file or directory I'm not too worried about defining who can play with the mac address since the only paired devices are ones I manually pair the first time and trust.Įxact commands: sudo rm /var/run/bluealsa/* d bluealsa Use the alsa device 'bluealsa'. This is the name that jack clients use to send audio to the sink. bluealsa-aplay: BlueALSA connection failed: No such file or directory I run the script with root permissions, and all the commands are the same as I would do manually. ![]() I need to remove the contents of /var/run/bluealsa, and then I start bluealsa under the a2dp-sink profile, then I run bluealsa-aplay for any mac address so any connected device can play music. Possibly the simplest example is to create a jack sink using the bluealsa default PCM: zita-j2a -j bluealsa -d bluealsa -p 1024 -n 3 -c 2 -L The command line arguments are as follows:-j bluealsa Use the name 'bluealsa' for the sink. sudo rm /var/run/bluealsa/ sudo bluealsa -p a2dp-sink & bluealsa-aplay 00:00:00:00:00:00 So I tried to put them in a shell script, but the script always says. Use Raspberry Pi GUI (pair bluetooth speaker, then select as audio output) or bluetoothctl commands to register speaker. This application runs in a Linux-embedded system and communicates with bluez. These are the significant pieces I have done so jack would start with bluetooth/bluealsa as the destination for output audio. I have it working, but it requires manual command entering. NoobNoob Asks: Connect to 'PCMAdded' and 'PCMRemoved' signals of bluealsa (Qt) I'm try to build a C++ application in Qt to capture audio streams from Bluetooth devices and play them to an ALSA playback device. I'm making my rpi 2 into a bluetooth adapter for a speaker, so a phone can connect and play music on the speaker. The best thing? The base model is only $20 $5!.ĭo you know a related subreddit?
