Realtek ALC887 and alsa (or OSS) not find

[Zendrael]

Hello all!

I've changed my main machine to a new Mini-Itx one but the sound card is not detected by Alsa or OSS.

The manufacturer says it's a Realtek ALC887 integrated audio but it is not recognized by Alsa neither OSS - both says that there is no soundcard on the machine. I'm running Core 5.3.

Should I have to download other extension to test it out? Or this card is not supported?

Thanks!

tce-load -iw pci-utils
lspci -nn

Post the line for the sound card.

Hi Mr. Gerald_Clark!
It says:

Code: [Select]

00:1b.0 Audio device [0403]: Intel Corporation Device [8086:0f04] (rev 0c)
This is the only line related to the audio.

ALSA support added in kernel commit e44007e0f97, included in 3.11 release. Perhaps you can force snd-hda-intel to load with a module parameter, not sure.

Edit: OSS does not have the support. Perhaps it works with just adding a PCI id.

Core kernel has no module for that  device ( 8086:0f04).

Hello!

Any plans for a future Core kernel from 3.11 series?

Or maybe a way to make it work? I saw that some distros force the use of a generic card on alsa... Is there a way to do that within Core?

Off hand I can't remember the exact chip model but I ran into a similar issue recently but found the latest Alsa modules supported my Realtek integrated audio audio chip and was able to force snd-hda-driver to load with a boot command   I'll check the chip model again and give feedback later

Hey Coreplayer2!

Your help will be much appreciated!

Waiting for your idea!

Thanks!

Sorry not much help here, though I'm using onchip audio via IEC958  S/PDIF,  in corepure64 lspci reports only "Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller - Kernel driver in use: snd_hda_intel"
Alsa on the other hand lists the chip as "Realtek ALC1150"  using alsamixer, you might try F6 to switch to your chip if supported..?

I'm using ALSA + Pulseaudio5 + paucontrol
with this command run at boot in xsession (otherwise no audio at all, and still alsa doesn't list the device even though it is apparently supported)
amixer -c 0 cset name='IEC958 Playback Switch' on (ensures S/PDIF is not muted on boot) 


I think after all my failures to enable my audio chip in the end i simply removed all alsa commands from the backup and installed ALSA in core32 & corepure64 then simply allowed alsa to configure itself  then installed/used the mixer to find the right volume control to enable, then installed Pulseaudio in core32 and pulseaudio5 in corepure64 + paucontrol

While this info might not be much help, I'd try alsamixer  because you might be looking for a device which is identified differently.

Looks like the forcing is done with "modprobe snd-hda-intel model=XXXX" with the model for your chip/hw.
