Please provide a backtrace using gdb

Also the output of valgrind would be interesting

1.5+dfsg1-7ubuntu0.1 and install mupen64plus-dbg. Also try to an strace and

mupen64plus-dbg is only useful to get the symbol names in the gdb and valgrind 
backtraces (which are required here). Valgrind can be used by prepending before 
the name:

$ valgrind mupen64plus /PATH/TO/ROM/asd.rom

gdb is a little bit more complex:

$ gdb --args mupen64plus /PATH/TO/ROM/asd.rom
....
(gdb) r
....
(gdb) bt
#0  _dl_debug_state () at dl-debug.c:77
#1  0x00007ffff7de0894 in dl_main (phdr=<value optimized out>, phnum=<value 
optimized out>, user_entry=<value optimized out>, auxv=<value optimized out>) 
at rtld.c:2368
#2  0x00007ffff7df199e in _dl_sysdep_start (start_argptr=<value optimized ou
....

And we would need the output after "bt". You can check the version of 
mupen64plus using 

$ dpkg -s mupen64plus

with gdb, command bt it goes to main-loop, and stops (gui not accessable)

if i start with --nogui, emulation starts and i get sound (sometimes underrun 
from also, working)

maybe gui blocks audio...

Thanks for the information - I will try to provide an updated package through 
ppa:sven-eckelmann/ppa-mupen64plus

I haven't found the problem yet, but should be possible. You can try to use as 
workaround 

$ mupen64plus --nogui /PATH/TO/ROM/asd.rom

I've disabled the SIGCHLD handler for now because we should not stop the 
emulation when another library stops helper threads. It can be found at 
ppa:sven-eckelmann/ppa-mupen64plus - You must get a FreezeException to get it 
into ubuntu. You can find more about that at 
https://wiki.ubuntu.com/StableReleaseUpdates

(The build may take a while)
