Lenovo Z575 Sound Problem

I am trying to get sound working correctly on a new Lenovo Z575. I followed the brief instructions on the ALSA wiki to make sure everything was unmuted. When I try to run speaker-test, I get the following:

# 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
Playback open error: -2,No such file or directory

Any advice is greatly appreciated.

Re: Lenovo Z575 Sound Problem

Did you try the recommendations in the configuration and troubleshooting section of the alsa wiki?

Re: Lenovo Z575 Sound Problem

I'm sure that if you google "alsa unable to open slave" you'll find something useful: http://www.google.com/search?q=alsa+una … open+slave

Also, you posted in the wrong category. This one is related to issues installing Arch Linux, not ALSA. Try the Multimedia and Games section (Audio/Video/Image issues, playback, creation and editing. Also for games support and discussion.)

I have made a personal commitment not to reply in topics that start with a lowercase letter. Proper grammar and punctuation is a sign of respect, and if you do not show any, you will NOT receive any help (at least not from me).

Re: Lenovo Z575 Sound Problem

Yes I did, and they didn't help. I did find the answer elsewhere though. It seems that on this particular machine the hdmi output and the standard speakers are on two separate devices. The hdmi device seems to be detected first by ALSA and is therefore the default device. Well, if you don't have anything plugged in, you get the above error. In order to mitigate this, you must create an .asoundrc file. My file contains the following in order to get sound to work:

defaults.ctl.card 1
defaults.pcm.card 1
defaults.pcm.device 0

In addition to this, if you use KDE, you have to change a line in the kmixrc file (located at ~/.kde4/share/config) in order to choose the second card as your primary. For some reason, the graphical interface will not allow you to do this.

MasterMixer=ALSA::HD-Audio_Generic:2
MasterMixerDevice=Master:0
