(Un)Fortunately, it appears the no bass bug (2) is a hardware problem. I also got no bass when testing in Windows.
As for the only top speaker bug (1), I tested two more options in /etc/modprobe.d/alsa-base.conf: - "model=auto" had the same behavior as the majority. - "single_cmd=1" didn't fix the speakers, and it broke headphone sensing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971224 Title: [HP Pavilion dv6 Notebook PC, IDT 92HD81B1X5, Speaker, Internal] No bass, only 2/4 speakers working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/971224/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
