[alsa-devel] Sound Blaster Audigy (snd_ca0106 Creative Labs|SB Audigy LS): How to use the mixer?

25 Aug 2008


      Hi,
Just trying to help a user with a problem and it seems to be down to the
fact that his SB Audigy LS does not have a "Master" or "PCM" mixer control.
I asked Lennart about this and he told that Takashi said he wanted to 
make sure that all devices have at least a Master vol control.
This one doesn't!
Please let me know what you need in order to fix this.
This is with 1.0.17... I can't see anything in the changelog that would 
suggest this is fixed in the 1.0.18rc1.
Please let me know if you need e.g. PCI ids etc. as I can ask the user 
to provide these.
Col
