do you get sound from from subwoofer after retasking node 0x1a ? since you have two headphone , speakers and subwoofer the current driver only create two volume controls for headphone And speaker you may need to retask one headphone Jack to UN connected if you want the driver to create volume controls for speaker and subwoofer https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/Documentation/sound/alsa /HD-Audio.txt `CONFIG_SND_HDA_HWDEP` is a useful option for debugging the driver. When this is enabled, the driver creates hardware-dependent devices (one per each codec), and you have a raw access to the device via these device files. For example, `hwC0D2` will be created for the codec slot #2 of the first card (#0). For debug-tools such as hda-verb and hda-analyzer, the hwdep device has to be enabled. Thus, it'd be better to turn this on always. `CONFIG_SND_HDA_RECONFIG` is a new option, and this depends on the hwdep option above. When enabled, you'll have some sysfs files under the corresponding hwdep directory. See "HD-audio reconfiguration" section below. http://git.alsa-project.org/?p=alsa- tools.git;a=blob;f=hdajackretask/README;hb=HEAD apply now button work only when driver is build with reconfig and the program can kill pulseaudio and can dynamic receive configure the driver the alternative is to use hda analyzer , just set pinctl of the subwoofer node to out and connected the node to one of the audio output , unmute the switch along the path and change the volume slider -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1332900 Title: [Alienware 18, Realtek ALC668, Speaker, Internal] Playback problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1332900/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
