New Revision: 339388
URL: https://svnweb.freebsd.org/changeset/base/339388
Log:
Fix for reception of large full speed isochronous frames via the transaction
translator, when using the DWC OTG USB controller driver. Make sure to re-try
getting the complete split packets until a DATA0 packet is received. Larger
isochronous frames may be split into multiple MDATA packets terminated
by a single DATA0 packet.

Hei,
I use a Sound Blaster Play 2 USB soundcard on a Raspberry Pi 2 and a
Raspberry Pi 3 to listen to internet radio streams (e.g. NRK, SR, BBC,
etc.). After this commit audio quality is deteriorated (strange noises). I've
tried mpg123 and moc.

Hi,
How many channels does your audio device have?
What sample rates are you using? What happens if you lower the vchanrate?
dmesg ?
What are the following sysctl values?
dev.pcm.x.rec.vchanrate: 48000
dev.pcm.x.play.vchanrate: 48000
x is 0 or 1.
--HPS
