The "Why setting CS8427_V > causes clicks and glitches?" comment of version 0.9.3 comes from an old > patch I sent to Jaroslav many months ago, when I had a similar problem with > an older 0.9.0something version of the drivers.

thanks for spotting this out. as you suggested above, i added the ews-specific initialization there. it just resets the RECVERRMASK register afterwards in ews.c. please try the cvs version. > I found also that the adriver.h file in version 0.9.4 includes the file > "linux/compiler.h", which is not present on older 2.4 kernels like my > 2.4.7. Everything seems to compile pretty well even without this include, > at least on 2.4.7, so may be a conditional inclusion is needed here. this should have been fixed on the cvs. it will create a dummy linux/compiler.h if not found. ciao, Takashi ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
