I confirmed, the on-board soundchip is Sound Blaster X-Fi Xtreme. But I think about it, the phenomenon that Carlos is describing as a problem is a natural one．Rather, do we ever use a speaker and a headphone at the same time? So, I looked into it, and found that Soundblaster offers a tool for windows that allows we to mute the headphone when using the speaker, and vice versa when using the headphone. https://crates.io/crates/sbz-switch/3.0.0 Regards. --- ┏━━┓彡 野宮 賢 mail-to: nomiya @ galaxy.dti.ne.jp ┃＼／彡 ┗━━┛ "Tim Cook, the C.E.O. of Apple, said earlier this year that he would not let his nephew join social networks.
