3. 
  
Actual results:
$ ls -l music.raw
-rw------- 1 jburgess jburgess 1744785408 Feb  9 00:35 music.raw

The problem and fix:
   "Gweled registers all drivers including DISK WRITER drivers, I have
removed RegisterAll and manually register all drivers which makes sense
(AudioFile, ESD, ALSA, OSS and NoSound).... Disable disk writer driver in MikMod
initialization"

Comment 1 Thorsten Leemhuis 2007-02-09 19:06:05 UTC

I don't see the problem locally -- that's odd, but well, software is odd sometimes. 

I contacted upstream about the issue. I'll probably apply the debian patch to my
package in case upstream has no plans for a new release in the near future.

Comment 2 Jon Burgess 2007-02-09 19:33:00 UTC

Looks like it falls back to the disk writer after other options fail. 
strace shows...

access("/dev/sound/dsp", F_OK)          = -1 ENOENT (No such file or directory)
access("/dev/dsp0", F_OK)               = -1 ENOENT (No such file or directory)
open("/dev/dsp", O_WRONLY)              = -1 EBUSY (Device or resource busy)
stat("music.raw", 0x7fff5b8c6bd0)       = -1 ENOENT (No such file or directory)
open("music.raw", O_RDWR|O_CREAT|O_TRUNC, 0600) = 16

I'm using KDE so artsd has the alsa sound devices open already:
[root@shark ~]# lsof -c artsd | grep /dev
artsd   18024 jburgess  mem    CHR              116,8               8023
/dev/snd/pcmC0D0p
artsd   18024 jburgess    0r   CHR                1,3               1883 /dev/null
artsd   18024 jburgess    9r   CHR              116,2               6927
/dev/snd/timer
artsd   18024 jburgess   10u   CHR              116,8               8023
/dev/snd/pcmC0D0p

Looking at the documented driver support in MikMod suggests that it doesn't
support artsd (but does support alsa, oss etc). If I kill artsd then the sound
in gweled works and no music.raw file is created.

Comment 3 Thorsten Leemhuis 2007-02-24 12:48:07 UTC

No answer from upstream; I applied to patches from debian to the devel and FC-6
branch and requested a build.
