Description Marco Fortina 2002-12-12 13:08:56 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)

Description of problem:
This probem discovered into file ac97_codec.c make not possible to configure 
the sound card using the codec SigmaTel STAC9700, eg. on laptop Dell Inspiron 

To solve this problem the instruction at line 148:

{0x83847600, "SigmaTel STAC????",	&null_ops},

must be substitute with

{0x83847600, "SigmaTel STAC9700",	&null_ops},

I've tested it on my Dell Inspiron 2600 and now the sound card works properly.

I hope, with this note, to help people who have the same problem.

Take care,
Marco Fortina

Ok interesting. As it happens I bought an inspiron 2600 3 weeks ago, and sound
does work for me (but with the latest erratum kernel, haven't tried the original
8.0 kernel much).. what exact kernel are you running ?
Comment 2 Marco Fortina 2002-12-13 06:07:45 EST
I'm running 2.4.18-18.8.0 kernel version. Without the changed described above 
there are no sound in gnome and volume control give a lots of errors such as:

bad key or invalid directory name

"....../SigmaTel_STAC????/.....: ? is not a valid character

Comment 3 Michael Lee Yohe 2002-12-13 10:19:04 EST
That's strange.  I also have an Inspiron 2600 - and this definitely WORKSFORME.
 Quirk perhaps?
Comment 4 Marco Fortina 2002-12-14 11:04:15 EST
Sorry.....Wrong Laptop model....

It's Inspiron 2650 NOT 2600


Comment 5 Arjan van de Ven 2002-12-14 11:07:44 EST
ah ok that would explain some ;)
Comment 6 Alan Cox 2002-12-16 00:30:46 EST
bug in gnome not in the kernel.
Comment 7 Marco Fortina 2002-12-16 10:22:54 EST
:-> ok I must agree with the answer of a Linux Kernel GURU....

Waiting for some pathes on Gnome.....


PS: is it possible, however, to modify le line as suggested? It's better 
reading the right name of Sigmatel Chip instead of STAC???? :->
Comment 8 Havoc Pennington 2002-12-16 13:54:21 EST
Fixed in newer gnome-media from rawhide.
