Correct. /dev/dsp1 implies you are trying to open the first playback channel on the second sound card in the system. Since I highly doubt that you have two sound cards, this fails. If a driver supports n number of channels, they would be accessed via /dev/dsp0.n-1. There are sound drivers out there, such as the SBLive driver, that support more than one playback and/or record channel. I'm not familiar enough with the ES137x driver to know whether it's the driver or the hardware that is limiting you in this case. > Has anybody configured their machine to use multiple dsp devices with > this card, or to allow multiple programs to open dsp0 at the same time? There are various sound servers that act as a proxy for the playback channel and allow multiple apps to connect to them simulatiously. Unfortunately, they each require their own protocol that your sound app must be aware of.
