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.

Or still problems? ---------------------------------------------------------------------- jborges - 11-18-04 19:04 ---------------------------------------------------------------------- Please take a look at attached file. Notice that both Line-as Rear and Line-In as Bass are not enabled. I have no means to turn it on or off. Also notice in the above result of amixer that most of the controls are set to mono.
