I have recently installed opensuse 12.1 in my Dell inspiron 1564 laptop. it shows two sound cards.
1.ATI R700 Audio Device [Radeon HD 4000 Series]
2.Intel 5 Series/3400 Series Chipset High Definition Audio
I have configured radeon as my primary sound card. But when I decrease (or) mute volume, it is not
changing. sound is still coming from the intel card. If I mute intel card(It is mentioned as internal audio in kmixer)
I can’t able to hear the sound.
Open Personal Settings (Configure Desktop) > Hardware > Multimedia then select Phonon from the list at the left
Here you can select the card you wish to be preferred for audio and video playback, just select the card of choice then click the Prefer button until it’s at the top of the list. Do this for both Video and Audio in the list at the left
You do know that the radeon r700 is hdmi audio from your graphics card right?
I’m not sure that hdmi audio is gonna work with your laptop speakers or headphones at all, it’s usually used for sending sound and graphics over the one hdmi cable to something like a tv
You’re probably better off setting the intel sound as the primary card in yast, preferred device in kde’s Personal Settings (called System Settings in most distros), and you’d probably also want to set the intel card as the master channel in kmix, then the volume icon in your tray and volume sliders on apps should work just fine
