No sound on Intel Corporation Lynx Point-LP HD Audio Controller

I've just installed Arch on a Dell Vostro 5470 (there's nothing on it's wiki page about sound). alsamixer shows only S/PDIF, S/PDIF 2, S/PDIF 3, which can' t be changed.

Re: No sound on Intel Corporation Lynx Point-LP HD Audio Controller

Set PCH as default card.

Re: No sound on Intel Corporation Lynx Point-LP HD Audio Controller

OK, but I don't know what you mean by that.

Reading the article I guess I have to write something like "options <module-name> index=0", but which module name to use (there's none with the pch somewhere in the name). I tried with almost all the "snd_*" modules and the result is exactly the same after a reboot.

Re: No sound on Intel Corporation Lynx Point-LP HD Audio Controller

Reread your own post. You have two cards using snd-hda-intel module, use vid and pid to set PCH as default. Step by step on wiki.

Edit: I took the PCH name from your 'dmesg | grep sound', people usually post 'aplay -l', but to determine the id one can also use:

cat /proc/asound/card*/id

The output of that should produce in your case:

HDMI
PCH

PCH is your analog output, HDMI is your digital output though graphics card. By reordering modules, PCH with be your default (first on the list). If you only use alsa, you can also use other methods described on the wiki, this method is recommended however, because when you choose to use a sound server like pulseaudio, it will not cause any additional problems.

Re: No sound on Intel Corporation Lynx Point-LP HD Audio Controller

I am having a similar issue except with an Intel Corporation Sunrise Point-LP HD Audio (rev 21). It has been very frustrating trying to get this to work. I used 'asoundconf-gtk' to produce my .asoundrc file because I couldn't get things working but it didn't help from what I can tell.

$ aplay /usr/share/sounds/alsa/Front_Center.wav
ALSA lib pcm_dmix.c:1099:(snd_pcm_dmix_open) unable to open slave

Re: No sound on Intel Corporation Lynx Point-LP HD Audio Controller

kodur,

Welcome to the Arch Linux forums.  Thank you for searching and finding a thread relevant to your problem.   
This thread is, however, three and a half years old and the original poster has not been back since shortly after this thread was created.  As things change fast in Linux, most of the underlying stuff has undoubtedly changed in the interim.

As such, I am going to go ahead and close this thread (without prejudice) and invite you to start a new thread on the topic which you will own.  If you feel appropriate, go ahead and link back to this thread in your new post.

Thanks.
