M-Audio Transit: alsamixer shows 100% and -0.5db at the same time !?

M-Audio Transit: alsamixer shows 100% and -0.5db at the same time !?

[Klaus Schulz]

Hi folks.

My M-Audio Transit shows at 100% and 0.5db attentuation in alsamixer at the
same time.

See below printout.

What could be the explanation for this behaviour?

"100%" just means that the control has its maximum value.

This is not a printout of alsamixer.

I can see neither "-0.5dB" nor "0.5dB attenuation" in there; it's 0.5 dB
gain.  (If you actually run alsamixer, it gets labeled with "gain".)


Best regards,

Hi Clemens.

BTW: I sent you corrections to sourceforge related to madfuload  
installation/udev setup/new driver for the transit some days ago. I am  
wondering if you still maintain the package.

Hmmh. I understand that. But how do I get around this? My goal would be to  
run the mixer at 0db.

Sorry. Below is an amixer output. Alsamixer says: gain -0.5
