Hi everyone,
After installing Fedora 22 on my Dell Vostro 5480, the speakers don't work, and the sound only comes out of the subwoofer. Here is the output of alsa-info.sh. After talking to "debianuser" on IRC, we found this workaround:
sudo hda-verb /dev/snd/hwC1D0 0x14 SET_PIN_WIDGET_CONTROL 0x40 # enable, set it to OUT sudo hda-verb /dev/snd/hwC1D0 0x14 SET_CONNECT_SEL 0 # switch to 0x0c sudo hda-verb /dev/snd/hwC1D0 0x14 SET_AMP_GAIN_MUTE 0xa000 # unmute left sudo hda-verb /dev/snd/hwC1D0 0x14 SET_AMP_GAIN_MUTE 0x9000 # unmute right
We suspect that it's a kernel driver bug. This makes the speakers work alongside the headphones (both at the same time) but I need help making it working when headphones are not plugged in.
Thanks,
Paulo
