Are you looking to play an MP3 file on a specific output device using PipeWire? In this article, we will guide you through the steps to play an MP3 file from the command line, ensuring that it routes through your desired PipeWire audio device.
Understanding the Problem
You may want to play an MP3 file while directing the sound output to a specific device configured in PipeWire. This is particularly useful if you're using multiple audio devices and want to isolate audio playback.
Original Code Scenario
Assuming you want to play an MP3 file named example.mp3, here is a simplified version of what the command may look like if you were just trying to play the file without specifying a device:
ffplay example.mp3
Updated Command for Specific PipeWire Device
To play an MP3 file through a specific PipeWire device, you would use a command line that specifies the audio device. Here's an improved version of the command:
ffplay -audio_device your_device_name example.mp3
Make sure to replace your_device_name with the exact name of the PipeWire device you wish to use, and example.mp3 with your actual MP3 file's name.
Finding Your PipeWire Device Name
To discover the available audio devices in PipeWire, you can use the following command:
pactl list short sinks
This command will list all available sinks (output devices) along with their names. Look for the device you want to use and note its name.
Playing the MP3 File
Once you've identified the device name, you can play the MP3 file using the command mentioned earlier. For example:
ffplay -audio_device alsa_output.pci-0000_00_1b.0.analog-stereo example.mp3
This will route the audio through the specified device.
Practical Example
Imagine you have two audio devices: your laptop speakers and an external USB sound card. You prefer to play your music through the USB sound card. Here’s how you would do it:
-
List Available Devices:
Run the following command to see your output devices:
pactl list short sinks -
Identify Your USB Sound Card:
Suppose the output gives you a device name like
alsa_output.usb-Logitech_USB_Headset-00.analog-stereo. -
Play the MP3 File:
Now, use the identified device name in your playback command:
ffplay -audio_device alsa_output.usb-Logitech_USB_Headset-00.analog-stereo example.mp3
This will play your MP3 file directly through your desired USB sound card.
