how to use nexuiz-sdl with a different alsa device ?

[liolak]

Hi there

I would like to know if there is an option for nexuiz-sdl to start it using a different alsa device ?

for example i can start mplayer using that different alsa device using the fallowing command:

Code: Select all

mplayer -ao alsa:device=equalized myfile.mp3

reason for doing this is to apply a alsa equalizer plugin to nexuiz.

os is linux.

thanks

after discussing about that issue with Lixivial, i learned that there is the -sndpcm option that does exactly what i want for nexuiz-glx. So my question is now : is there an equivalent feature for nexuiz-sdl ?

You can somewhat control SDL with environment variables, just search the web. You might try setting the AUDIODEV env var to the ALSA device name, for example (provided SDL is actually using the ALSA audio driver).

thanks parasti, that was a good lead but i cant figure the proper syntax to use my device.

searched in google a lot, but most cases i found where using some default devices.

for example if i set:

Code: Select all

export SDL_AUDIODRIVER="alsa"
export AUDIODEV=hw:0

it works, as in i have sounds. but obviously its not using my equalizer device. i tryed numerous way of pointing it to my "equalized" device, like:

Code: Select all

export AUDIODEV=equalized



but nexuiz always dont like it and dont play sound at all.

Try

Code: Select all

plug:equalized

. Does that help?

thanks for helping lda17h, unfortunately it does not work.

here is the exact error it gives me

Code: Select all

S_Startup: initializing sound output format: 44100Hz, 16 bit, 2 channels...
ALSA lib pcm.c:2171:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_equal.so
Wanted audio Specification:
   Channels  : 2
   Format    : 0x8010
   Frequency : 44100
   Samples   : 2048
Failed to open the audio device! (No available audio device)
S_Startup: sound output initialization FAILED

it says equal instead of equalized because thats the real name im using, i used equalized here just for more context.

i checked for "/usr/lib/alsa-lib/libasound_module_pcm_equal.so" and yes it exist.

Just having the plugin isn't enough. You also need to define an ALSA pcm device by the way. Oh i saw that you have it. Do

Code: Select all

aplay -L


to get a list of devices available on your system anyways..

Thanks for your suggestion though, I appreciate it
