One thing I have noticed, that in rtcw muilt-player the sound works ok but when you exit the game, it doesn't exit cleanly. The driver is kept open and in use until I issue an interrupt in the terminal window that the game was run in. Not sure if this is significant or not but I thought I better mention it just in case. >>Have no option but to kill it at this point.

Unfortunately I get the same original "cannot open /dev/dsp" error message. I went back and specifically added the directive for SND_CONFIG_CS46XX_ACCEPT_VALID to cs46xx_lib.c, but the problem persists. If I try it without the patch in, the 'cannot open' error message goes away. The patch seems to not use the SND_CONFIG_CS46XX_ACCEPT_VALID options anymore but instead uses directives of the form CS46XX_BAx_... .I wonder then if SND_CONFIG_CS46XX_ACCEPT_VALID should be define somewhere else or is it retired for this round of testing?? I tried compiling the cvs without the patch in and configured it with debug=full, when I get the hang in rtcw single-user mode, no error message is produced either on the console or in the system log. There is no core dump produced either. I can't seem to get the system to cough up an error message so we can move forward with this. > > >Takashi > regards Darryl > _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
