Dell XPS 17 (9710) "dummy output" pulseaudio

Hi,

I am very new to linux, recently got a new Dell XPS and decided to install Arch Linux. Everything looks good except sound. I have made sure that sof-firmware and alsa-ucm-conf packages are installed as per Arch Pulse audio guide. But nothing seems to work, pulse shows "Dummy Output", so laptop speakers does not work. Headphone jack does not work either.

I also tried some other solutions which talk about doing the following

 /etc/modprobe.d/alsa-base.conf

options snd-hda-intel enable_msi=1
options snd-hda-intel dmic_detect=0
blacklist snd_sok_skl

Did not help me. Any help would be much appreciated.

Re: Dell XPS 17 (9710) "dummy output" pulseaudio

remove alsa-base.conf, reboot post the output of 

sudo dmesg | grep -iE 'snd|sof'

make sure you are up to date there was a new sof-firmware release recently.

Thanks, I removed alsa-base.conf before posting, should have mentioned that. I did reboot after that,

Re: Dell XPS 17 (9710) "dummy output" pulseaudio

See this bug report and link: https://github.com/thesofproject/linux/ … -893692661 you'll probably need to either patch your kernel or try to update using linux-mainline or so.

Thanks for the information, useful read, at this moment, guess I will wait for 5.15 kernel, meanwhile use headphone via bluetooth.

Re: Dell XPS 17 (9710) "dummy output" pulseaudio

I just got a fancy Alienware x17 and installed arch with kernel 5.16.1-arch1-1 and had a dummy output like this.  I had to install these packages: alsa-firmware, sof-firmware, and alsa-ucm-conf


see https://unix.stackexchange.com/question … mmy-output
