Ubuntu – Subwoofer doesn’t work on Dell Inspiron 17R after upgrade to 13.10


After upgrading from 13.04 to 13.10 Dell's Inspirion 17R subwoofer stoped working.

In Ubuntu 13.04 was workaround by adding in the file /etc/modprobe.d/alsa-base.conf next line:

options snd-hda-intel model=ref

This issue was discussed here: How to activate subwoofer in Inspiron 17r?

After update previous workarounds don't help and I get no sound from any speaker in this case.

Is there some other fix for the latest version?

  • I have a Dell 17R as well and had to use hdajackretask to get the subwoofer to work again.

    1. Install hdajackretask by installing alsa-tools and alsa-tools-gui.
    2. Open hdajackretask.
    3. Select "Show unconnected pins".
    4. Find pin 0x10 and choose "Internal Speaker (LFE)".
    5. Click "Install Boot Override".
    6. Restart and you should be good to go.
