SADA emulation and 96khz

[Tomservo]

I'm running an X-Fi in my system. Everything seems to work fine, ignoring the ossdetect running to get vmix working. It however seems, having looked at the source code, that the SADA emulation can't upsample beyond 48khz. It would be nice, unless a new beta of the X-Fi driver will be released soon, that at least upsampling support to 96khz for the two common sample rates 44khz and 48khz would be implemented. It's mainly to get Flash work normally again on an X-Fi (micky mouse effect).

Thanks for considering.

edit /kernel/drv/vmix.conf and change the rate to 96000 and run ossdetect again.

I still get the Micky Mouse effect and these:

I think it's this:

Code: Select all

int sadasupport_rate = 48000;

...lots of code...

int
sadasupport_attach (oss_device_t * osdev)
{
#ifndef SOL9
  audio_sup_reg_data_t data;
#endif
  int instance;
  /* extern struct cb_ops ossdrv_streams_cb_ops; */

  sadasupport_mixer_srs[1] = sadasupport_rate;   /* Set the maximum rate */

I've patched that value for fun in a hex editor, since setting up a build environment takes some time and effort. Doesn't change anything.

When vmix is loaded, the Micky Mouse effect is distorted. Without vmix, it's Micky Mouse undistorted. That's just strange.
