Most of the things doing 5.1 are like the WM8580 - they use separate data lines rather than TDM, as far as I can tell a lot of 5.1 systems out there do this by hooking up multiple stereo CODECs in parallel as slaves rather than by using a single 5.1 CODEC. --/QKKmeG/X/bPShih Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJUv46OAAoJECTWi3JdVIfQL5kH/3Lro2Nlc7Mll2+Fr2TX1lLj DRBueBhvDHQEuzRs9KBhCXkmUsKhHDCOTRrbz+Eh/bXYtcXEygpAalXWmDfkMW+5 RZ20y5VSVuW2dK4ZVEOa6DnJUeURkZQenQuMFt6ENmWgfF9kgJDMbNbv/75b/UX/ iiTDxCS+G23p5BvGnIrsqby3Ke/DwBU2W/6eZMtX2d1MfdKP4tZOJgj7u7+tFWc+ BOrtpKgYqohpSCD9lHb6k3KN719rcPoLkcv8EqpcaZWs91tC0g7AffSeR0xnePkE UtEWGiecz3XdCzHi7/lvTU5Ef7A04lw3r0OiLpN9mCRUqi/ZbQDqdPYkzXe5dUI= =p/Tt -----END PGP SIGNATURE----- --/QKKmeG/X/bPShih-- --===============0313823143913275777== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline --===============0313823143913275777==--
