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.

When I say it is not enable I want to mean that this is a dead control. I can not push the M key to mute or umute it. Neither it turns off by pushing that key. Another thing is there is no way to control the volume in these controls. The columns above their names stay empty all the time. It not possible to move the colors inside that columns. Really sorry for the incovenience. It would be more inteligente just to forget the whole troble. But, I just like to understand what is going on. Thanks anyway to stay in this strugle with me. ---------------------------------------------------------------------- tiwai - 12-07-04 18:33 ---------------------------------------------------------------------- Hmm, the constant value is OK. They have really no values but only switches. But non-working switches are of course unexpected problems. Please attach /proc/asound/card0/cmipci for debugging. Try to run the following: amixer set 'Line-In As Bass' off amixer set 'Line-In As Rear' off And compare the above proc file. Any changes?
