no sound in slackware 14.1 on new i7 laptop with haswell hdmi

I saw this similar thread http://www.linuxquestions.org/questi...-a-4175497740/ but I am unable to resolve this issue on my own.

My son just bought this laptop from system76 and I have set it up per his wishes to dual boot slackware and windows 7. Everything but the sound is working in slackware.

In KDE, if I right-click KMix in the system tray, click "Select Master Channel" and then select "Current Mixer --> HDA Intel PCH" and then run the following I hear sound.

Code:

aplay -D plughw:1,0 /usr/share/sounds/alsa/Noise.wav 

Playing WAVE '/usr/share/sounds/alsa/Noise.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

At a loss how to troubleshoot this.

You want to set card 1 device 0 as the default sound device.
http://docs.slackware.com/howtos:har...s_on_slackware

once you get the sound in kde using the mixer try opening a terminal and at the cli use the "alsactl store" command.
If that dosn't work check out http://docs.slackware.com/howtos:har...s_on_slackware

That worked earlier today. I have the following in /etc/asound.conf

Code:

pcm.!default {

        type hw

        card 1

        device 0

  }

  ctl.!default {

        type hw

        card 1

        device 0

  }

I was able to hear sound from youtube in firefox. Now it stopped working.

alsamixer no longer opens for me either.

Code:

bash-4.2$ alsamixer 

cannot open mixer: Invalid argument

Please post the output of 'cat /proc/asound/card*/id' as it should show the id's being used for the devices.

It may be preferable to create a /etc/modprobe.d/snd-hda-intel.conf containing something like the below to configure the devices.

Code:

alias char-major-116 snd

alias snd-card-0 snd-hda-intel

alias snd-card-1 snd-hda-intel



options snd cards_limit=2



options snd-hda-intel id=PCH index=0

options snd-hda-intel id=MID index=1

The id's shown in blue may need to edited.

can't get the laptop back from him now to test this. he is obsessed with civilization v and some paradox games.

I arrived at this same situation with an S-76 laptop just a few days ago. Go over to Installation and check "Slackware64-14.1 ALSA Configuration?" In the last post there I try to outline what I did that solved my problem. I am running Xfce but I do not think that is relevant to this issue. I think allend is on to it. The essential step is to have Alsa recognize and work with the proper card.

Thanks. I'll see if I can wrench the laptop away from him long enough to try your setup when he comes home from college on the weekend. Also, I wasn't quite correct that sound isn't working at all in firefox anymore. I setup two users on his computer. Sound in firefox works for the first user account I setup but not for the second user.
