> (In reply to darnellkeithj from comment #42) I will nevertheless try to get back to a working configuration with some kernel and report back.
INSPIRON 531 NO AUDIO OUTPUT DEVICE INSTALLED ERROR INSTALL
tried different kernel module options for snd-hda-intel) so my working state was never a vanilla install with some updates. What makes tracking this down a bit trickier than just booting with earlier kernel packages is that I have fiddled with both alsa and pulse on the system (e.g. But they did a couple of weeks later and that's when I found this ticket for ALC287. I did not make any notes of the occasion as I assumed there might have been a recent kernel or some other package update, and did not expect any regressions to occur. I had already prepared for not having sound as I had read the Arch Wiki page, and was really struck with a surprise as one day after playing with merely the ubuntu sound settings (fiddling with system sound volume) the speakers suddenly started working. > Could this be possibly related to a BIOS update? > IIRC, and I've always had this problem. > About how long have you had your Legion? I've had mine since August 6th If we can reproduce it, we'll be a lot closer to a solution.

Did you allow internet updates during install? If you still have the ISO you used, I'd also like to confirm the hash of the file. > I can paste the hidden BIOS HD audio settings for this configuration if > updated but I could not find any meaningful culprit. > My guess is that there might have been regression due to some package being > (headphones have always worked), until it suddenly stopped working again. > A notable thing is that i *DID* have speaker audio for a couple of weeks > My issues are also present on Legion 7i (Legion 7-15IMH05 Type 81YT). > Or is everyone on this same machine so far? > Is everyone experiencing this on machines other than the Lenovo Legion 7i? I am happy to run the script again (or any other tool) from a different distro/kernel combination, please just let me know what would be helpful. My alsa-info.sh results (from Manjaro on 5.6.15) are here: I *am* able to get sound via headphones and HDMI (though I believe HDMI is via a different sound card).Īlso, I can see that there is some kind of sound activity occurring when I look at pavucontrol (the reddish-orange bar that indicates a sound is playing), but there is no actual sound produced from the speakers. In all cases, I get no sounds from the speakers (running speaker-test, playing music, etc.). In each case, I made sure to disable Auto-Mute in alsamixer, and turn all volume levels to maximum. I have tried various Linux distros and kernel combinations, including Ubuntu 16.04, 18.04, and 20.04, with both the default and mainline kernels (5.7.x & 5.8.x), and Manjaro with 5.6.x, 5.7.x and 5.8.x kernels.
I get no sound via the speakers of my Lenovo Legion 7i laptop, which alsamixer tells me is using a Realtek ALC287. Little modification to the `linux-max.patch` to fix sound for Legion 7i, S740, Yoga 9i
