#814 linux mic support is a joke

[skas]

At the last puzzle, as the final move, one has to blow in the microphone to make the wind blow.
Using the microphone, I can see the two people and the SUN moving, but nothing happening.
I cannot finish this game because of that particular problem.
So, bug or misconfiguration of my microphone ?
I'm joining the dsv file this time, the save game is two puzzle away from the last.
see http://www.gamefaqs.com/portable/ds/file/938420/52101 for explanation of how to finish the two last puzzles

[skas]

Save File for last puzzle.

the mic code in linux is terrible and i dare say nonexistent. im not sure why the faq says that it is supported. youd best assume there is no mic in linux, nor proper support for mic noise

Will try to reproduce with your save game but from from my own experience it recognizes the blow just fine. Just to be sure are you compiling with libasound right?

[Magliocchetti Riccardo]

skas, can you confirm that you have built with libasound please?

[skas]

Yes I confirm it was linked with libasound.
In the configure I have :
checking for ALSA... yes
And at the link the -lasound is present.
ldd src/gtk/desmume gives :
libasound.so.2 => /usr/lib/libasound.so.2 (0x00007f6d7fc67000)
Maybe there is nothing wrong with desmume. I'll check twice.

skas, does the openal microphone work for you?

[BlCa]

Same problem using svn3266 built with alsa support. Mic just doesn't work with Desmume (but works properly otherwise).

BlCa, i've asked to try the openal code (./configure --enable-openal) and not the alsa one.

[BlCa]

Updated source to svn3276, compiled with --enable-openal and tried launching desmume:

BlCa thanks for testing, could you please file a new bug report with the segmentation fault you are experiencing with openal over alsa over pulseaudio? Also please compile desmume with symbols and post a full backtrace.

[BlCa]

Well, with svn3279, it doesn't segfault anymore but mic doesn't work properly either.
Now, it's like desmume detects constant mic blowing, even when mic is unplugged from the computer and muted in the mixer.
Sorry, can't provide you with full backtrace as installing all debug symbol packages on this computer is a no go.

Apparently building DeSmuME with an outdated version of gcc fixes this, but I'm not inclined to find out; thankfully the only moment when the mic was actually needed in the first Ace Attorney game is once the game is already over!
