Attaching alsa-info from Dell Vostro 5470. It is also missing the subwoofer, which is at pin 0x17.
In addition, DAC node 0x03 is mono for some reason. Probably it is expected to run both headphones and front speakers through DAC node 0x02 and the sub speaker through 0x03. ** Summary changed: - Low audio output on Vostro 5460 (with Ubuntu pre-loaded) + Low audio output / missing subwoofer on Vostro 5460/5470 (with Ubuntu pre-loaded) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1211920 Title: Low audio output / missing subwoofer on Vostro 5460/5470 (with Ubuntu pre-loaded) Status in “alsa-driver” package in Ubuntu: Triaged Bug description: I have been using a Dell Vostro 5460 for a while.
