I Haven't Any Sound Post Install

[hjozwiak]

Hello again,

 

I installed Funtoo to my box, and it was a total breeze! But I've hit a roadblock; I haven't any sound. I've installed media-sound/alsa-utils, app-accessibility/espeakup, and the sys-kernel/linux-firmware packages. After I did that, I've added espeakup and alsasound to the default runlevels. But, upon umounting the partitions and rebooting, I haven no sound but a working system. I spoke with a sighted friend and he informed me that there are no volume bars for either of my sound cardss; one is a SoundBlaster Recon 3DI and the other is some form of HDMI card (I believe it is an nvidia one). Have I skipped a step somewhere? Has anyone else encountered a similar issue?

 

Thanks,

 

Hunter

Apollogies; I had to run in a chroot on account of my friend not being here to read the link. But hopefully this will help diagnose the issue.

If your speakers are connected to the sound card with 3.5 mm jack and not HDMI the default sound device 0 needs to be switched from HDMI to PCH CA0132 Analog.

Open a terminal, as root:

echo "options snd-hda-intel index=0" > /etc/modprobe.d/snd-hda-intel.conf

Reboot, open alsamixer.

Verify the settings are for PCH, unmute,raise all levels and test your sound.

Okay. I just made that configuration file with the suggested tweak. But I still have no sound; indeed, I can't even change the volume from within the chroot. All I see is a bar for sp/pdif, which I don't know what that is for. It was off, so I turned it on. Speakup, when I try to change the bar, just says oo oo oo and no change to the volume occurs. Under playback devices, nothing is listed, either; this is a headscratcher indeed.

Hi!

This might not work in chroot in case you are using Sysrescue CD. To my knowledge their cd still not including sound drivers.

When you booted into your new installation make sure your are in audio group.

[hjozwiak]

Is it necessary to put root in audio? I haven't made a user yet; the system is really fresh.

[cardinal]

Users need rw to /dev/snd for audio.

User root owns /dev/snd with rw permissions, it is not necessary to add root to audio group.

Regular users added to audio group are granted rw permissions to /dev/snd

funtoo rj # ls -la  /dev/snd

When you chroot your using the host kernel and drivers you booted into, not root filesystem that you mount and then chroot into.

You have to boot funtoo's kernel for the configuration to have any effect with funtoo's snd-hda-intel kernel module.

Are those supposed to be underscores as opposed to dashes? Also, I have no capture devices according to some friends that were trying to help me; I guess eudev may have missed loading some of the firmware.

[Oleg Vinichenko]

eudev and same goes for udev does not do firmware loading anymore, it is done by kernel own firmware loader starting with kernel version 3.8. Could you, please, provide your lspci -v and also kernel configuration. 

[hjozwiak]

Please find attached.
