Does the cable box audio out have any option to set a fixed -vs- variable output level.
Frequently on TV's the fixed level is quite a bit higher than the highest varable output level. This might have the result you want if the option is available to try.

One other idea, Run the cable box audio out into your VCR and then run the VCR audio out into your 950. The VCR may output a more uniform final volume level than the cable box.
