Description Brian Maloney 2003-06-13 03:52:15 UTC
Using XMMS's libMikMod plugin, in 16-bit resolution mode, it produces only
garbage noise.  Selecting 8-bit mode fixes it right up.  This leads me to
believe it may be an endian-ness issue.

Reproducible: Always
Steps to Reproduce:
1. Start XMMS
2. In the Preferences dialog, make sure the Resolution for libMikMod is set to
16-bit
3. Open a MOD file and play

Actual Results:  
Got hideous staticy noise out of the speakers.

Expected Results:  
Clear playing of the MOD file.

Portage 2.0.48-r1 (default-ppc-1.4, gcc-3.2.3, glibc-2.3.2-r1)

It _is_ an endianness-bug.  I looked into the mikmod-source but can't find anything how to change it.  Usually mikmod runs on ppc (even on MacOS), but I don't know, if they switched off the usage of 16-bit mods.

I will leave this bug as new.  Hopefully another dev with other skills may look in it ;-)
Comment 2 Pieter Van den Abeele (RETIRED) gentoo-dev 2003-07-15 06:15:00 UTC
looking into this now 
Comment 3 Pieter Van den Abeele (RETIRED) gentoo-dev 2003-07-15 09:13:24 UTC
hm, the code to the mikmod plugin was last changed in '99 - and from looking at it, I see no suspicious code.

could this be a sound driver issue?
Comment 4 SpanKY gentoo-dev 2003-09-12 20:56:11 UTC
could you try xmms-1.2.8-r1 ?
and if it doesnt work post an offending mod file ?

Brian, please see spanky's comment.
Comment 6 Brian Maloney 2003-09-15 06:19:43 UTC
Sorry, Gentoo has crashed horribly on my Mac and I haven't been able to get it booting again.  If anyone else can test this, it was EVERY mod file which was causing the problem, so you shouldn't have a problem reproducing it with the older version.
