• Looking at linux sound to try fix quake linux. Need oss /dev/dsp device, but oss has been replaced by ALSA (see below). ALSA replaced OSS, when OSS went proprietary, but subsequently OSS4 was released under opensource, but the integration has been minimal
  • OPTIONS:
    • Trying to emulate OSS wih padsp or osspd
      • padsp provides cap 0x5100 (DSP_CAP_TRIGGER|DSP_CAP_MULTI|DSP_CAP_DUPLEX)
      • osspd provides cap 0x5300 (DSP_CAP_TRIGGER|DSP_CAP_MULTI|DSP_CAP_REALTIME|DSP_CAP_DUPLEX)
        • App <—> /dev/dsp <—> CUSE <—> osspd <—> ossp-padsp <—> pulseaudio
        • Verified installation by cat /dev/urandom > /dev/dsp
        • followed Bug #1857810 “osspd no longer works: ERR: failed to connect cont...” : Bugs : osspd package : Ubuntu
          • Test game, ETQW Demo 1.4:

            https://cdn.splashdamage.com/downloads/games/etqw/ETQW-demo2-client-full.r1.x86.runhttps://www.splashdamage.com/games/enemy-territory-quake-wars/ A) If the game fails to launch with "etqw-rthread", remove libgcc_s.so.1, libjpeg.so.62, libstdc++.so.6 from the game's directory; install libsdl1.2debian:i386, libjpeg62:i386, libstdc++6:i386 B) After launching and creating an account, quit the game. Edit ~/.etqwcl/base/etqwconfig.cfg: seta s_driver "oss" c) Relaunch the game with "etqw-rthread", test voice input in Settings and in-game.

      • neither seem to provide DSP_CAP_MMAP which is needed for quake

10 April

• Fixed GLX initialization (extension limit ed8974a08fceab21e126bbe88f36479406cd4db2)
• Fixed full screen GL (fe4e67025e7b76b2c697877b137252ea61f1c2a3)
• TODO: Restoring video mode on shutdown is not functioning (desktop is left at whatever resolution game ran at)
