Description: I'm using Kurumin 3.2 (a Brazilian flavor of Knoppix) in a ASUS P4B533 with CMI8738 sound chip, processor is Pentium IV 3.0 GHz, 512 RAM and 120 Maxtor Ultra Dma Hard Disk. Also I use Kde 3.2.3 on Kernel 2.4.25-klg. This Linux installation works in a dual-boot with windows xp. The sound works fine (all 6 channels respond very well)under windows xp or 98. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Trying to configure my sound to work I noticed some problems with alsamixer: 1 - As I can see, there is a conflict for the output. I can't see Line-In been used to output as bass and the same Line-In used to output as rear (L/R). 2 - I think Line-In would be used to output as Rear (L/R) and Mic to output as Bass/Center. What is happening is that: when one uses a 6 channel system there is no sound in the conflicted Line-In as bass and Mic as center. The little sound that goes there is squeezed from Line-In as rear. The sound in bass and center is full of noise. Impossible to listen. I took some snapshots (2) to show you what I'm talking about. Please take a look on them in the attached files.

I wrote something and attached a new picture. The picture is there but nothing went togheter. Maybe I forgot to push the add note button. Sorry about that. What I wanted to tell you is: in the new picture you can see more clearly that line-in as bass and line-in as rear are not enabled. There is no bars on them and neither the doted lines above the empty bars. The samething happen with 3d control and mic as. Again, sorry. ---------------------------------------------------------------------- tiwai - 12-02-04 19:25 ---------------------------------------------------------------------- Both are enabled in the new pictures indeed, too. You'll see 'MM' on the top of volume bar and '[Off]' in the item name when the switch is disabled. Try to push 'M' key on the corresponding volume.
