Problems running linux binary file
« Thread Started on Nov 11, 2010, 6:01pm »

I've been trying to launch the binary file for pSX, but I keep getting this error message.

Code:
[src/linux/sound.cpp, line 215]: 'snd_pcm_hw_params_set_access(pcm_handle,hwparams,SND_PCM_ACCESS_MMAP_INTERLEAVED)' returned 'Invalid argument'
pad=0
Segmentation fault (core dumped)

If it helps to know this, I'm running a 32-bit system with Fedora 14 installed in it.

Make sure you have the ALSA driver installed.

I have exactly the same problem. ALSA is up and running.
32 bit Mandriva 2010.2 Free.

pSX has three Linux dependencies: OpenGL, ALSA, GTK, GTKGLEXT, and libxml2. Make sure each of these is installed, and up-to-date.

Make sure you've run chmod +x pSX to turn the binary into an executable

That particular error comes from PulseAudio. In order to get past it, you need to kill the PulseAudio daemon (pasuspender will NOT work in this case). Here's how:

first, create the text file ~/.pulse/client.conf with the following line in it:

Code:
autospawn = no

Then issue the following command before running pSX:

Code:
pulseaudio -k

and the following command after running pSX:

Code:
pulseaudio -D

All that said, with the newest versions of Ubuntu, the linux version of pSX *still* doesn't work, giving me the following error:

Code:
pSX: pcm_params.c:2285: snd_pcm_hw_refine: Assertion `pcm && params' failed.
Aborted

I hope this eventually helps somebody...and if anyone has gotten past the second error, please, let me know.

Thanks, Ultima, I hadn't seen that, but it doesn't really help me....I already know how to disable PA properly (it does, however, point out a problem I hadn't known about). The second error I get happens even with PA disabled.

That said, the Windows version of pSX works well in Wine, so I'll use that instead until 1.14 comes out (or someone figures out a workaround for the "pcm && params" error).

it doesn't give me any problems now, accept for the case when i have something already running, ie Slacker radio. I have to stop it before i start pSX or it gives me this error:

Code:
[src/linux/sound.cpp, line 582]: 'snd_pcm_open(&pcm_handle,dev->info->device_fname,SND_PCM_STREAM_PLAYBACK,0)' returned 'Device or resource busy'
pSX: pcm_params.c:2274: snd_pcm_hw_refine: Assertion `pcm && params' failed.
Aborted

That was the point of my linking; I wasn't telling you to disable PulseAudio.
