 Posted: Tue Oct 12, 2021 4:49 am Post subject: No sound: Intel Tiger Lake LP |
 |
|
I just got a new laptop the other day. It is a Lenovo IdeaPad 5 14ITL05. I installed Gentoo with the default/linux/amd64/17.1/hardened (stable) profile. While using pulseaudio, I realized nothing was coming from the speakers. I emerged pavucontrol, and noticed that no sound card was detected. Did some research, and found I needed to install sys-firmware/sof-firmware. After emerging that, the speakers showed up in pavucontrol, and in pamixer. pavucontrol showed volume coming from the speaker, yet I could not hear anything. When plugging in a headphones with the headphone jack, pavucontrol detects a headphone being inserted, and appears to redirect output there, but the same happens: no output can be heard. Windows 10 has working sound, and I tested Pop OS 21.04 on a live usb, and it had sound as well. Pop OS has a 5.13 kernel, while I am using a 5.10 kernel. Genkernel, I have not customized it yet. My windows manager is DWM 6.2

If there is any more information you need, please tell me, and I will be happy to oblige (I have never posted in a forum before). I have been looking all day fruitlessly. Thank you in advance. |

lspci detects your audio device.
Just for info - take a look at the output of "dmesg" and also your logs at "/var/log/messages".
Is there something related to "hda", "sound", or "audio" that shed light?
If everything seems OK, maybe you need to compile some additional module in your kernel or add a use flag to pulseaudio? Revisit the Wiki: https://wiki.gentoo.org/wiki/PulseAudio
What are your useflags for pulseaudio btw?

togooroo,
Welcome to Gentoo.
Your dmesg looks good. The codec is detected.
Run alsamixer and mute all the controls.
Unmute Master, Front and PCM and set their sliders to about 70% - Now test.
Your sound card can do sound over HDMI or to the built in speakers but not both together.
When both are enabled only HDMI works.

| Thank you NeddySeagoon. I went into alsamixer and I attmped to change those settings, but I did not see any sliders labeled Front or PCM. This is on the sof-hda-dsp device. Moving over to the PulseAudio device, I saw one slider. After muting and unmuting that the audio is now working. I will reboot and see if this saved |

It appears that I need to unmute the Master slider in alsamixer to make audio work. Does this mean that I am not using pulse at all, and directly using ALSA?
p.s.
equery uses pulseaudio
| Code: |
* Found these USE flags for media-sound/pulseaudio-13.0-r1:
U I
+ + X : Build the X11 publish module to export PulseAudio information through X11 protocol for clients to make use. Don't enable this flag if you want to use a system wide
instance. If unsure, enable this flag.
- - abi_x86_32 : 32-bit (x86) libraries
+ + alsa : Add support for media-libs/alsa-lib (Advanced Linux Sound Architecture)

- - gconf : Ensure gnome-base/gconf is present for pulseaudio GConf to GSettings module automatic migration (keeping the user configuration)
- - gdbm : Use sys-libs/gdbm to store PulseAudio databases. Recommended for desktop usage. This flag causes the whole package to be licensed under GPL-2 or later.
+ + glib : Add support to dev-libs/glib-based mainloop for the libpulse client library, to allow using libpulse on glib-based programs. Build the GSettings PA module.

Did you selected right audio card in alsamixer? [F6] |

Here are my pulseaudio USE flags, which are verified to work in my configuration (I have an AMD X399 board with built-in audio device). Compare and try changing those and emerge pulseaudio again:

togooroo,
Pulseaudio is a wrapper around alsa.
I'm not sure if pulseaudio requires you to add alsasound to the default runlevel or not.
That's the service that saves and restores your mixer settings across reboots.
