Thread: Sound or Pulseaudio issues on emulators/games

    Default Sound or Pulseaudio issues on emulators/games

    I used to play some of my PS1 games using an emulator called "pSX emulator" back on openSUSE 11.3 x86_64. It just required some libraries (albeit 32-bit ones) to be installed and be given execution permissions to be able to run.
    Now I tried it on 12.1 x86_64 and I got this error:

    [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

    I was told there were some sound changes since 11.4, I don't remember if related to ALSA/Pulseaudio, but in the end I thought that could be the cause of the error.
    I was recently suggested to kill Pulseaudio with the command
    Code:
    killall -9 pulseaudio
    whcih could also work for other many games to work properly on recent Linux distributions.

    I'm not at home right now, thus haven't tried it. But I wanted to ask, would that command work? What sound changes were made in openSUSE to get that error above?
    Thanks for your help.

    Apparently it didn't work. Any help about this? Thanks.

    I would use an emulator that is... well, still developed (PCSX-Reloaded). But yes, probably PulseAudio can not be used through the ALSA API if the app is trying to use MMAP.

    I don't know if that emulator allows to select the sound device. But the easy fix is to just use ALSA. Remove the "alsa-plugins-pulse" package, and perhaps reboot. With that ALSA apps will use ALSA. That will conflict with PulseAudio, but you can disable it temporally or just remove it.

    I'd also like to use a still-alive emulator, but PCSX-Reloaded seems to have kind of slow development and several issues on still various games, unless I'm wrong...
    I liked pSX emulator because it's very easy to use and has wide game compatibility, being only surpassed by ePSXe, though it also seems a dead project...
