[MPlayer-dev-eng] [PATCH] add alsa9 mixer seletion (fwd)

[Roland Kuhn]

Hi!

I've noticed that the -pre1 alsa9 code always uses card 'default' and control 
'PCM' for the mixer. Well, I usually use hw:1,0,1 for playback, so I wrote the 
following patch:

+          card = strdup(mixer_device);
+          mix_name = strchr(card, '/');
+          if(mix_name) {
+            *mix_name++ = 0;
+          } else {
+            mix_name = "PCM";
+          }
+        } else {
+          mix_name = "PCM";
+          card = "default";
+        }
+      }
+
       if(ao_data.format == AFMT_AC3)
        return CONTROL_TRUE;

==============================

Any chance something like this could go in? Works like a charm for me ;-) Now 
I can use "-mixer hw:1/Master" so that the 0/9 keys operate on the correct 
control.

Ciao,
