Attached, the script file which tests all available (listed) models against snd-hda-intel , reloading and playing a sound each time to see if they work. N.B. None of the model values works for Dell N5110, but I'm looking into this on the alsa-devel list.
To try all possible models in an automated way, first of all manually edit your /etc/modprobe.d/alsa-base.conf using... gksudo gedit /etc/modprobe.d/alsa-base.conf ...and make sure the last line is a snd-hda-intel model line. Here's an extract showing the last four lines from my copy of alsa-base.conf with the last two lines having been added by myself... # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=-2 # CH added following https://help.ubuntu.com/community/HdaIntelSoundHowto options snd-hda-intel model=test Download the attached testcards.sh script, change it to executable and then run from within a terminal, when it will automatically try every possible value of the 'model' attribute by changing this last line, reloading alsa and playing a sample. If you hear a sound, you know that the model value currently showing in the terminal output is useful chmod u+x testcards.sh gksudo ./testcards.sh In my case none of the models solved my silent speaker on N5110 (Q15R) problem so I've started a dialogue with alsa-devel to try and go deeper into the HDA controls which can be introspected from my hardware to see what else can be toggled, but for many I gather, changing the model and reloading alsa is a useful gambit. ** Attachment added: "A script to try every possible model against snd-hda-intel" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/914290/+attachment/2669363/+files/testcards.sh -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/914290 Title: Sound card silent on Dell N5110 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/914290/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
