Yandex Browser can open audio files with the following extensions: mp3, wav, m4a, wma, ogg, x-m4a, mpeg.
Audio on the side panel
In Yandex Browser, you can view a website and listen to music playing in another tab at the same time. To avoid switching between tabs, click on the side panel. In the control panel that appears, you can pause or resume a track, as well as switch to the previous or next track in the playlist.
If music is playing in multiple tabs, the panel displays all the tracks, and you can switch between them.
You can control the sound of a separate tab:
To mute the music, click Звук вкладки включен.
To turn the music back on, click Звук вкладки отключен.
If you have multiple tracks playing and don't have time to pause them one by one, click Mute all tabs.
Note
Music doesn't stop playing on a muted tab.
