I have an old laptop (with dual boot) with two speakers on the front and one big speaker at the back.
In windows all the speakers work and the sound is loud, but in linux -based distros only the front two speakers work.
** aplay -l gives this output.

I even tried using hdajackretask but it didn’t work, alsamixer doesn’t detect the rear speaker.
what might be the issue?
