I've seen that the ice1724 driver (which is based on ice1712) is unable to mmap on /dev/dsp. The trick is to switch the order of your cards so that /dev/dsp is attached to your ac97 on-board first, instead of your ice1712. If you make 'alias snd-card-0 snd-intel8x0', you'll probably find the game will work happily. later, Steve Mr.Freeze wrote: > Hey, > I'm using an "ice1712" soundcard (with whom I satisfied) on a Shuttle box, whose > "intel8x0" audio chipset powers I'm trying to "revive", in order to attempt > again to make the game Enemy Territory work at last, as it returned the > following error, when using the better soundcard of the two: > > ------- sound initialization ------- > /dev/dsp: Input/output error > Could not mmap /dev/dsp > ------------------------------------ > > One reported on the ET forum (on the thread "ET / Linux: no sound!") that it is > supposed to be due to this "ice1712" driver, quoting the "Advanced Linux Sound > Architecture - Driver Configuration Guide" > > MMAP on ICE1712 driver > ---------------------- > ICE1712 supports only the unconventional format, interleaved 10-channels 24bit > (packed in 32bit) format.
