Hello, thank you for improving your player !
I tried it on a Wiz , the display-off feature seems not to work , the screen freezes only .
The sound control is effective from 1 to 15 , from 16 to 115 i can’t hear a variation on the volume . 15 is the max and the sound stays as low as the previous version .
Keep working on it :)

@sebk: Thanks for the feedback. That’s weird with the display-off feature. Probably, I broke it just before the release. I will fix it of course. As for the volume control: This has been reported by others as well. It seems the Wiz uses a different mixer channel for volume control than the GP2X. I will try to fix it.

If you or anybody else reading this, wants to help a little (I still do not own a Wiz, so I can’t test it on the real device), you can send me the debug output of Gmu. The easiest way of doing that is to edit the gmu-wiz.gpu file with a text editor to redirect the debug output to a text file, like so:

Changing the line

LD_LIBRARY_PATH=libs.wiz/ ./gmu

to

LD_LIBRARY_PATH=libs.wiz/ ./gmu >debug.log 2>debug.log

That will generate a text file called debug.log which might be helpful for me.

#!/bin/sh
cd `dirname $0`
LD_LIBRARY_PATH=libs.wiz/ ./gmu >debug.log 2>debug.log
cd /usr/gp2x
./gp2xmenu

gmu-wiz.gpu writes like that ?

It crashes the Wiz at the loading screen when I launch gmu :(

@sebk: Could you try it with this file again?

Maybe there is a problem with the file format. This can happen when using a text editor that does not support unix linebreaks, such as Notepad.

It should not crash the Wiz as all it does is redirect the standard out and standard error output to a file.

Here is the debug file:

(edit by wejp: removed the unimportant parts of the log to make it a little shorter)

Thanks for the log. Indeed it was very useful. The problem is, that the Wiz sound driver is broken. Although there is a master volume channel (a volume value can be read for that channel), it reports it has no volume channels available at all. That’s why Gmu does not choose a channel for hardware volume control.
Now that I know that, I can force Gmu to select the master channel on the Wiz.

I hope you will release it soon :)
