Last night, I installed Zorin OS 15.3. Everything is running smooth except for the sound. When I test speakers in sound settings, sound if coming from the left channel but not from the right channel. However, this is not happening in Windows 10.
I researched on the internet to find any clues, but to no avail. I even tried searching for the Dell sound drivers, but there aren't any.
Furthermore, I just can't figure out what could be wrong. Any help will be highly appreciated.
Thanks in advance
