Re: [Alsa-user] help with alsa support for realtek ALC203

[Jesse <kan...@ya...>]

 Thanks for your note. /proc/asound/cards gives:
 
  0 [ICH6           ]: ICH4 - Intel ICH6
                       Intel ICH6 with ALC203 at 0xd0000000, irq 177
 
 which, as far as I can tell, is exactly what it should be so nothing
 suspicious there. Running "amixer contents" gives the info below
 which I'm not sure how to interpret. Should I switch all of the
 "values" flags to "on"?
 
  Thanks,
 
   Jesse

The preferred player for testing is aplay (not that it's likely to make
any difference).

What is the output of "amixer contents"?

If it's listed in /proc/asound/cards then it's supported.

You should use a matching (or later) version of alsa-lib, but it
shouldn't matter much.
