My netlink is down at present so I can't check this. If this refers only to SPDIF *output* then this is still OK - EAPD is on the same pin as SPDIF *input*. However, if the machine can also do SPDIF input via this "adapter" then that may indicate that the ALC260's EAPD functionality isn't used since that pin is required for SPDIF input. Then again, having said that, I think it is possible they could use the same pin for both with some clever engineering. Anyway, I'll try to get a patch done up soon to test the theory. Then we'll know for sure. Regards jonathan ------------------------------------------------------------------------- Take Surveys. Earn Cash.
