[Solved] Alsa on a Lenovo Thinkpad 525

Hi all,

Long time lurker here. I finally moved my Arch install out of VirtualBox under Ubuntu onto my laptop and it's all going well, except for sound. I've read the relevant wiki entry, searched various forums and tried different things. I admit I know very little about soundcards/mixers/etc and I'm at a loss of what to do now.

My setup:

Linux arch64 3.2.9-1-ARCH #1 SMP PREEMPT Thu Mar 1 09:31:13 CET 2012 x86_64 AMD A8-3500M APU with Radeon(tm) HD Graphics AuthenticAMD GNU/Linux

on a Lenovo ThinkPad 525

I'm running KDE. I don't have [testing] enabled.
I have installed alsa-oss, alsa-utils and alsa-plugins.
I have unmuted everything using alsamixer.

My problem:
I have sound in VLC, system beeps and notification on startup but no sound in Firefox. Neither HTML5 nor flash videos give sound in Firefox.
Kmix also doesn't show volume control, just "IEC958". Under Mixer in Kmix  changing the Master setting of "HD-Audio Generic" does change the volume.

I get errors when I run speaker-test -c 2

speaker-test 1.0.25

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave

The output of cat /proc/asound/cards is:

Edit: More information

I'm using systemd and I have alsa-store.service enabled

Could anyone point me in the right direction to getting sound working system wide? Any help would be greatly appreciated.

Re: [Solved] Alsa on a Lenovo Thinkpad 525

Thank you for a super fast and helpful response!
It took me a few attempts to get it right. Last time I tried it I got the card id wrong.

For others: I created the following file


with the contents

options snd-hda-intel id=Generic1 index=1

I rebooted. I accepted the KDE prompt about devices being removed. I unmuted everything with alsamixer again.
Sound now works in VLC (audio settings to default) and Firefox, and also in both at the same time. Kmix also works as expected when I set the Master Channel to HD Audio Generic. Headphones jack also works.
