Subject: [Bluez-devel] a2dpd produces choppy audio with Digitus dongle, OK with D-Link
Date: Fri, 09 Mar 2007 17:12:05 +0100 [thread overview]
Message-ID: <45F18755.7040307@exon.dyndns.org> (raw)
I followed the suggestion to try alsaplayer instead of XMMS, and managed
to get a2dpd working. XMMS, aplay, ESD, and Xine all fail, but at least
I can prove that things work in principle.
However, when I try using my Digitus DN-3008M1 instead of my D-Link
DBT-120, the sound is choppy, alternating half a second of sound with at
least a second of silence, making it unusable.
Does anyone know what causes the choppiness? On the host side, the
configuration is identical. The Digitus dongle is a CSR chipset, which
is supposed to be the good stuff:
hci0: Type: USB
BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 192:8 SCO MTU: 64:8
HCI 18.2.1
Chip version: BlueCore3-ROM
Max key size: 128 bit
SCO mapping: HCI
Attached is a big chunk of the error messages a2dpd prints out. It
looks bad, but I don't have the faintest clue what it all means.
Thanks for any help,
Mat
