The BDL is comprised of a series of Buffer Descriptor List Entries. There must be at least two entries in the list, with a maximum of 256 entries 3.6.3 Buffer Descriptor List Entry Each Buffer Descriptor List Entry (BDLE) contains a description of a buffer which is a piece of the whole cyclic stream buffer. The buffers described by the BDLE must start on a 128-byte boundary, and the length must be an integer number of Words. your two hda controllers will use same buffer size(buffer time 1 seconds) at stereo 48000Hz since One second * 48000Hz * 4 bytes align at 128 byte boundary but 44100Hz does not align at 128bytes</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
