mono/stereo problem with i810 chipset?

Hello all,

I am trying to play an asf stream on a computer with a i810 chipset. This=20
fails. Logging output is at the end of this mail.

Playing (stereo) MP3 files from the local LAN is fine.

As you can see in the log, the OSS renderer fails and reports that the chip=
set=20
cannot be put in the requested mode.

Then AviPlay attempts to use the SDL renderer. When this starts to play, I=
=20
hear audio at double speed for a few seconds, then silence, then audio at=20
double speed, and so on.

I have browsed thru the old mail archives, and it seems that there is some=
=20
problem with mono in the i810 chipset.

I wonder whether the i810 is really unable to play mono streams, or that th=
ere=20
is a problem in the ioctl call to control the i810, like a wrong return val=
ue=20
or so.

Is there maybe a workaround for this problem? Unfortunately I need an asf=20
_stream_, so I cannot first save the stream and convert it to stereo for=20
playback.

Any comments appreciated, even a confirmation of this problem. (so I know I=
 am=20
not alone :-) )

        If you wish to store the stream into a local file
        you may try to use this before starting aviplay:
                export WRITE_ASF=3D1
        this will create /tmp/asfXXXXX with received data
