 Posted: Fri Apr 09, 2021 6:17 pm Post subject: no soundcards found |
 |
|
Hi, I cant seem to get my soundcard up and running.
lspci -k
| Code: | Audio device: Intel Corporation Tiger Lake-LP Smart Sound Technology Audio Controller (rev20)
Subsystem: Lenovo Tiger Lake-LP Smart Sound Technology Audio Controller
Kernel driver in use:snd_hda_intel |
kernel .config
https://dpaste.com/DRGQF57YT
aplay -l returns
| Code: | | aplay: device_list:274: no soundcards found... |
Cant find my card in alsamixer either. So I guess I'm missing something in my kernel.
I am fairly new to gentoo, any help with troubleshooting would be greatly appreciated. |

Hi
Welcome to Gentoo Forums
Please try
| Code: |
emerge -av sys-firmware/sof-firmware linux-firmware intel-microcode
iucode_tool -S --write-earlyfw=/boot/early_ucode.cpio /lib/firmware/intel-ucode/*
|
Update initramfs and grub.
Reboot

Thank you for the fast reply.
Emerged the packages and ran the iucode tool. Ran grub-mkconfig -o /boot/grub/grub.cfg and did a reboot. I dont have an initramfs.
same output from aplay -l |

Maybe you need an initramfs to load the firmware...

Ok. I added support for initramfs in kernel, updated grub and:
| Code: | gbox /boot # genkernel --install --firmware --kernel-config=/usr/src/linux/.config initramfs
* Gentoo Linux Genkernel; Version 4.2.1
* Using genkernel configuration from '/etc/genkernel.conf' ...
* Running with options: --install --firmware --kernel-config=/usr/src/linux/.config initramfs
* Working with Linux kernel 5.10.27-gentoo for x86_64
* Using kernel config file '/usr/src/linux-5.10.27-gentoo/.config' ...
* Current kernel's LOCALVERSION is set to ''; Will ignore set --kernel-localversion value '-x86_64' because kernel was not build ...
* initramfs: >> Initializing ...
* >> Appending devices cpio data ...
* >> Appending base_layout cpio data ...
* >> Appending util-linux cpio data ...
* >> Appending eudev cpio data ...
* >> Appending devicemanager cpio data ...
* >> Appending auxiliary cpio data ...
* >> Appending busybox cpio data ...
* >> Appending modprobed cpio data ...
* >> Appending firmware cpio data ...
* >> Appending modules cpio data ...
* modules: 0 modules copied. Is that correct?
* >> Appending linker cpio data ...
* >> Deduping cpio ...
* >> Pre-generating initramfs' /etc/ld.so.cache ...
* >> Compressing cpio data (.xz) ...
*
* You will find the initramfs in '/boot/initramfs-5.10.27-gentoo.img'.
* WARNING... WARNING... WARNING...
* Additional kernel parameters that *may* be required to boot properly:
* Do NOT report kernel bugs as genkernel bugs unless your bug
* is about the default genkernel configuration...
*
* Make sure you have the latest ~arch genkernel before reporting bugs. |
reboot yet again, initramfs seems to load at boot, still no soundcard.
| Code: | * >> Appending modules cpio data ...
* modules: 0 modules copied. Is that correct? |
Is this the issue? |

GGekko,
The sound driver is in two parts. The first part | Code: | | CONFIG_SND_HDA_INTEL=y |
provides the snd_hda_intel driver.
You also need | Code: | | # CONFIG_SND_HDA_CODEC_HDMI is not set |
for digital sound outputs.
| Code: | | # CONFIG_SND_HDA_INTEL_HDMI_SILENT_STREAM is not set |
is a good idea for digital outputs too. It avoids the first few seconds of the sound stream to a digital output being lost,.
For analogue audio, you need an analogue codec too.
| Code: | # CONFIG_SND_HDA_RECONFIG is not set
# CONFIG_SND_HDA_INPUT_BEEP is not set
# CONFIG_SND_HDA_PATCH_LOADER is not set
# CONFIG_SND_HDA_CODEC_REALTEK is not set
# CONFIG_SND_HDA_CODEC_ANALOG is not set
# CONFIG_SND_HDA_CODEC_SIGMATEL is not set
# CONFIG_SND_HDA_CODEC_VIA is not set
# CONFIG_SND_HDA_CODEC_HDMI is not set
# CONFIG_SND_HDA_CODEC_CIRRUS is not set
# CONFIG_SND_HDA_CODEC_CONEXANT is not set
# CONFIG_SND_HDA_CODEC_CA0110 is not set
# CONFIG_SND_HDA_CODEC_CA0132 is not set
# CONFIG_SND_HDA_CODEC_CMEDIA is not set
# CONFIG_SND_HDA_CODEC_SI3054 is not set |
and they are all off.
Build all the codecs in. When one works, it will be listed in alsamixer.
