It seems that my kernel (2.6.10-1.737_FC3) llimits the number of dsp devices to be 8. One for my on-board sound card (/dev/dsp) and then 7 more (/dev/dsp{1,2,3,4,5,6,7}). Trouble is, I have a system that needs to access 8 off-board codecs.
How do I increase the number of allowable /dev/dsp devices? Do I need to reompile the kernel? Or is there some configuration file that can be changed?
The output from the syslog for the 7th and 8th offboard devices is:
