Ali5451 problem with mixer

[Rafal Dejewski]

Hi,
I have a problem with alsa mixer on kernel 2.5.51 and alsa-lib, alsa-utils 
0.6rc6. Whenerver I try to run alsamixer the following message appers in 
console and alsamixer would not start:
$ alsamixer
ALSA lib simple.c:944:(simple_add1) helem (MIXER,'IEC958 Playback 
Switch',0,0,0) appears twice or more
alsamixer: function snd_mixer_load failed: Invalid argument

I found out that disabling this check in simple.c in alsa-lib allows alsamixer 
to run and work (well, for me). 
Unfortunatelly I can't test spdif connection. Oss emullation mixer works ok. 
This happens also with ali5451.c rev.1.23 from cvs.
This problem was also reported here: 
http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg05094.html

Help appreciated,
Rafal

could you try the latest cvs version?  perhaps this is because of the
name confliction between the internal switch and ac97-codec's switch.
if my guess is correct, it should have been fixed now.
