#1605 closed defect (invalid)

AdLib outputs where?

Reported by: SF/routsikka Owned by: SF/ender
Priority: normal Component: Port: Linux
Keywords: Cc:


Using Debian Unstable version of ScummVM 0.6.0 (Mar 14
2004 18:01:37)

Documentation states:

"7.1) Playing sound with Adlib emulation:
---- -----------------------------------
By default an Adlib card will be emulated and ScummVM
will output the music as sampled waves. This is the
default mode for most games, and offers the best
compatibility between machines and games."

But where does Adlib emulation's output actually go,
because I have no sound or music? I haven't found a
switch to set Adlib module's output option.

If I try to use Adlib emulation, I get these error messages

WARNING: Sound mixer initialization failed!
WARNING: MIDI driver depends on sound mixer, switching
to null MIDI driver!

I have ALSA and its OSS-emulation configured. The
working ALSA device is hw:0,1. Sound drivers are from
2.6.2 kernel.

To whatever the SDL library decides to use, I guess. I think
that the first message means that SDL_OpenAudio() failed for
whatever reason. If so, it's unlikely to be a ScummVM bug.
Are other SDL applications able to play sound on your computer?

Sounds to me like you have permission problems on /dev/dsp

As erik suggested, this error indeed means that the SDL
OSystem interface was not able to create a sound device. I
would suggest apt-get source'ing ScummVM and placing the

warning("Couldn't open sound device: %s", SDL_GetError());

after "if (SDL_OpenAudio...) {" and before "return false;" in the
source trees backends/sdl/sdl.cpp. Then rebuild the package
for an better error message regarding your problem.

I'll make sure this debugging line goes into ScummVM 0.6.1

Closing bug, this is a system configuration issue.
