Re: No sound - Solaris x86

Concerning audio on Solaris/x86, I see that the problem is that ogle
is trying to set the sample rate to 48000 in

  info.play.sample_rate = audio_info->sample_rate;

but the SoundBlaster cards (except the AWE32?) supported in Solaris 8
only go to 45000.  This gives

      setinfo: Invalid argument
      FATAL[ogle_audio]: ogle_ao_init: 

   corresponding to the code 

     /* set the audio format */
     if(ioctl(instance->fd, AUDIO_SETINFO, &info) == -1) {
       perror("setinfo");
       return -1;
     }

   from ogle-0.9.2/libogleao/solaris_audio.c.

Substituting something lower for the sample rate allows ogle to
continue, although the sound is of course too slow.

It is possible that the "audio mixer audio personality module
interface" on Solaris/x86 is supposed to be used by ogle (?):

     The audio mixer supports the new  multi-stream  Codecs  that
     have become available recently. Examples of these Codecs are
     the  Crystal  Semiconductor   4410/4422   and   the   Aureal
     8820/8830.  These devices have DSP engines on them that pro-
     vide a great many features, such as sample rate  conversion.
     Therefore  each  play/record channel is mapped to an indivi-
     dual channel straight into the Codec  and  the  audio  mixer
     doesn't  do  any  sample  rate  or  encoding  conversion, as
     described below. However, the programming interfaces  remain
     the same and applications cannot tell the difference between
     a multi-stream Codec and a traditional Codec.

This appears to be far beyond my feeble talents.  Is there another
workaround?  Ogle does not seem to support rate conversion.  I'm
uncertain if the AWE32 (one of the few cards listed in Sun's
compatibility list) would solve the problem.  Maybe Solaris 9 has
better hardware support
