ALSA sound problems in notebook with HDMI output

[VAA]

Netbook Acer Aspire One 725.
Installed OS Silex 14.1RC1, but the same problems I see when installed other systems of Slakware 14.x family.
Sound works in skype, but not works in Midori, Firefox and in all mediaplayers.
Google search say that same problem can bee in noutbooks with HDMI interface for external monitor/TV
what have two soundcards and first, default card is for HDMI. I have:

Code: Select all

...[~]$ lspci | grep Audio
00:01.1 Audio device: AMD/ATI [Advanced Micro Devices, Inc.] Wrestler HDMI Audio [Radeon HD 6250/6310]
00:14.2 Audio device: AMD [Advanced Micro Devices, Inc.] FCH Azalia Controller (rev 01)

Actually I have corrected the situation for Audacious by selection of right sound interface in audio setup of that player.
But I can not find the way how to select analog sound output as default for all the system.

There is no way to correct situation selecting of drivers loading because both cards use the same driver.

I have found the advise select default card

to disable HDMI sound by sanding to kernel

Code: Select all

snd_hda_intel.enable=0,1

Sorry, I can not understand how to do that...

Please help me!

Open the Salix application menu, chose "System" and then "ALSA sound card".

Choose the sound card you want to use as system default, click "OK"

Restart your session by logging out and then back in again.

You may need to adjust the Xfce4 mixer settings to be able to control the selected sound card, click the volume icon to open the volume control program and choose the sound card you want to adjust using the drop down menu.

Hope it works for you!

Now it work.
My mistake was that I did not reboot the system.
