[Solved] No sound from speakers - headphones work just fine

[JustinTL]

Hello -

I recently got a Lenovo Yoga 7i for the sole reason of installing Linux, primarily to learn it. For the most part that has gone well but I don't have any sound from the speakers while the headphones work just fine. While I still had Windows on the machine the sound worked fine however I had this problem when I put Ubuntu on the laptop and also with Mint (which I'm currently running). I've searched the forums and Google and this seems to be a common issue and while I've seen a lot of suggested remedies, I can't seem to find any that have worked for me.

If it helps, I ran inxi -Fxxxrz to get some system information and have this output

I've tried looking at AlsaMixer and hdajackretask but just seem to hit dead ends on this. Hoping someone on this forum might be able to take a look and provide some help?

Thank you!

On my system I have to unplug the headphones to get sound out of my external speakers...

I'm pretty sure that's true on all systems. While I'm pretty sure your response is snarky, thank you for bumping me up!

You've likely tried these cmds for AlsaMixer:

Code: Select all

Sudo alsa force-reload 

Check if automute is enabled:

Code: Select all

alsamixer

And while the interface is up, check if all the bars are high.

[JustinTL]

Yep, tried it.

Just tried it again though after reinstalling Mint. Made sure everything is up. Automute is disabled.

I just ran "inxi"on my Lenovo Thinkpad T460...Here is the Audio portion:

Audio:
Device-1: Intel Sunrise Point-LP HD Audio vendor:
Lenovo driver: snd_hda_intel v: kernel bus ID: 00:1f.3 chip ID: 8086:9d70

This will give detailed info on drivers:

Have you visited the Alsa website? https://alsa-project.org/wiki/Main_Page
Much info there...Sound cards supported, etc.

Just to close this out. Today I got the update to the Linux kernel 5.13 which resolved my sound issue.
