[alsa-devel] No sound for HP Pavilion DV4z

[aeleneski at comcast.net]

Alright. Well, it again seems like a no go. 
Ran all the commands, still no sound. Upon starting Amarok, I receive the error "xine was unable to initialize any audio drivers." 

Then also when I do aplay -l I get: 

**** List of PLAYBACK Hardware Devices **** 
card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI] 
Subdevices: 1/1 
Subdevice #0: subdevice #0 


Attached is the alsa-info text. 

Thanks again. 
Andrew

Ah no, you don't have to restart the system at all. 
Maybe I wasn't clear enough. 

The sequence above itself will make your sound system already usable. 
(and you don't have to probe_only=1 option.) 
Just use your sound apps after the sequence above after checking the 
mixer status. 

If it still doesn't work, run alsa-info and attach the outupt again. 
Also, show the kernel message, too.
