found trouble in "Windows Audio Session (WASAPI) sample"

Question

in this sample:

Windows Audio Session (WASAPI) sample

i found this (WASAPIRenderer.cpp, line 304):

if (m_DeviceProps.hnsBufferDuration < hnsMinBufferDuration)
        {
            // using MINIMUM size instead
            m_DeviceProps.hnsBufferDuration = hnsMinBufferDuration;
        }
        else if (hnsMinBufferDuration > hnsMaxBufferDuration)
        {
            // using MAXIMUM size instead
            m_DeviceProps.hnsBufferDuration = hnsMaxBufferDuration;
        }

"else if (hnsMinBufferDuration > hnsMaxBufferDuration)"

is there a mistake or catching some hardware issues?

Answer 1

Without knowing that sample at all, I would agree that this looks like a bug. I'll see what I can find out about it.

Answer 3

hnsMinBufferDuration and hns MaxBufferDuration - this gets from endpoint audio rendering device properties

Answer 4

BTW, I believe the sample has been updated already.
