Actually I'm fairly certain the hardware doesn't get calibrated. > Register definition on page 36, How To Calibrate on page 67. probably. it did not seem necessary on the cs42311, cs4232, cs4236, cs4237 (all the ones i have) but maybe they have changed something. > Considering I'm the one that has the problem and can replicate it, have > been studying the code looking for the appropriate place to calibrate. > mss_attach() in ad1848.c looks like a good place as the calibration in this case, do it in the pnp attach routine for the 4235 (cs423x_attach() or something) similar to what is done for the opti931. cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
