According to http://unix.stackexchange.com/questi...cted-in-debian

I have motherboard based on z170 chipset which have next string in specs:

Realtek ALC887 codec

it has 5.1(3 connectors) and stereo(1 connector) connectors not counting Line In and microphone connectors on back side.

I have 5.1 sound system connected to right connectors. But detected audio cards are next:

lspci -v |grep udio

00:1f.3 Audio device: Intel Corporation Device a170 (rev 31)
06:00.1 Audio device: NVIDIA Corporation GK104 HDMI Audio Controller (rev a1)

One of which is named as:

Built-in Audio digital Stereo IEC958
and other

GK104 HDMI ...bla bla bla 5.1 .
in KMix Select Master Channel dialog window.

Am i right that 5.1 ALC887 is not detected here at all?

GK104 corresponds to Nvidia GTX 680 video(which i have) audio chip?

How to get detected 5.1 audio for ALC887 if i am right about previous questions?

Also

lsmod|grep snd
Gives next output:

snd_hda_codec_hdmi 45118 1
snd_hda_codec_realtek 67127 1
snd_hda_codec_generic 63181 1 snd_hda_codec_realtek

Kernel version is 4.2
pulseaudio version is 5.0

updated to pulseaudio version 7.0 from testing - nothing changes.

Hi...

Could you give us the slightly more detailed readout of...

Thanks!

00:1f.3 Audio device [0403]: Intel Corporation Sunrise Point-H HD Audio [8086:a170] (rev 31)

I created another issue for Ubuntu sound on askubuntu.com

http://askubuntu.com/questions/69154...y-because-of-n

I was able to get sound after installation but after several reboots

"Built-in Audio Analog Stereo" device become "Built-in Audio digital Stereo IEC958" - S/PDIF device in pavucontrol utility.

It seems to me that it is some kind of alsa driver option controls which devices are detected but i don't know which options does that. Or maybe it is pulseaudio responsibility because alsa device is already working.

aplay -L

always shows

surround51:CARD=PCH,DEV=0
HDA Intel PCH, ALC887-VD Analog
5.1 Surround output to Front, Center, Rear and Subwoofer speakers

I was able to play sound in surround51 with aplay in both Ubuntu and Debian. So drivers work well.

Hi...

Is your issue resolved? If so, please mark this thread as "SOLVED" by clicking on "Thread Tools" directly above your initial post. Thanks!

Regards...

No. Not resolved.

Drivers work well but I need a way to tell pulseaudio which device to use/see when it is runned so it would use "Built-in Audio Analog Stereo"(for example) instead of "Built-in Audio digital Stereo IEC958"(S/PDIF)

Hi...

I think this is handled through ALSA, not PulseAudio. What is the output of...

Regards...

It is strange but after reinstallation of pulseaudio from testing aplay -l listing changed.

aplay -l

$ pulseaudio --version
pulseaudio 7.0

Now surround device is listed in KMix Select Master Channel dialog. Sound works well.

How that happened and why i don't know but I think I would like get an answer to the main question anyway.

Or is it a bug then "aplay -l" lists surround51 device but not lists it in KMix Select Master Channel dialog?

Hi...

I'm not sure how you would change the digital to analog in this case, since both are registered as "card 0."

However, the instructions here might be helpful...

ardvark, i already told you once that this way you are discarding the extra information you get with the -k switch.
you have to allow trailing context to get the kernel module:
your lord and savior probably isn't doing such a great job after all.

vyacheslav, my last post wasn't directed at you, but it's still good that you posted that output.
it seems to be an alsa issue, yes.
2 soundcards.
you have to tell alsa which card is the default card.
i don't remember the exact command, but search for it, it's fairly simple. there even used to be a gui for that iirc.

Hi...

I vaguely recall someone telling me about how to construct a similar command concerning sound, I believe, but please bear in mind that code is not a strong area with me.

Actually, He is doing a wonderful job, just in ways you can't see because you don't know me. Why insult Him for what you feel was my mistake?

Regards...

why are you requesting it then?


i wasn't insulting him...

Because I do know a little of the lspci commands and what I do know, I'm willing to use to help others with. If you feel your command is better, simply ask the OP to post the output of it. There's no need to get angry with and insult me in the process.

Regards...
