Hello Everyone,
Recently, I implmented an audio capture filter in avstream
architecture under XP, and then I implment it's volume node to get a volume
control on my capture filter. After a lot of try and error, I finally made
the volume scroll bar work. However, the volume range of scroll bar does not
hornor the lower bounds of KSPROPERTY_STEPPING_LONG, but honor the upper
bound. I have tried to implment BASICSUPPORT handler, but it did not work. I
found somebody run into the same problem here, if this were solved, could
any one help?
P.S: The volume range can work normally under Win7.
Thank you in advance~
