Bug 143415

In SuSE 10_x64, I think there is a problem with sound mixing from 32-bit applications (when running a 64-bit kernel).  I used the script recommended in bug 117989, namely

LD_PRELOAD="$LD_PRELOAD:${exec_prefix}/\$LIB/libaoss.so" exec "$@"

but I get multiple warnings

ERROR: ld.so: object '/$LIB/libaoss.so' from LD_PRELOAD cannot be preloaded: ignored.

Now, if I put 'exec "$@" '   on a separate line, I don't get this error, programs invoked through this script seem to run, BUT skype still "monopolizes" the sound card and flashplayer and realplayer play muted, the latter two without any error output!  Similarly, 32-bit java (invoked through firefox, which has to be 32-bit so it can play flashplayer and realplayer) runs but if another application is using the sound card, java's sound output is muted (eventhough ALSA compatibility is installed).

Now, if I try to invoke programs through "esddsp -m <program>' (as discussed in bug #117989), I get this error:

ERROR: ld.so: object '/usr/lib64/libesd.so.0' from LD_PRELOAD cannot be preloaded: ignored.

and the sound mixing from 32-bit application fails.

These four 32-bit programs (skype, flashplayer, Realplayer, and 32-bit java), as mentioned above, are few but very important. (I also tried gizmoproject, skype's competitor, which, like skype, has oss output, with similarly disheartening results.)  I use a 64-bit laptop, a Compaq Presario, with the nVidia chipset and nVidia  64MB video card, so a sound card with hardware mixing is not an option for me.  The 32-bit MPlayer seems to be very well behaved with either alsa or esd output.

If I remember correctly, I was able to do software mixing of the above applications under artsdsp in SuSE 9.3 x86_64 despite similar errors about unloadable libaoss libraries (!!!!), but I am not sure how and why.
