I didn't know I had SPDIF... There are 3 connectors on my sound card: microphone, headphones and a blue one. There is a symbol which makes me think of an antenna (similar to http://www.wpclipart.com/telephone/antenna.png without the pedestal) and no SPDIF written under it.
According to wikipedia (http://en.wikipedia.org/wiki/Sound_card#Color_codes) it should be an analog line level audio input, so I don't think it's SPDIF (as you wrote it's an optical audio output) except if they use the same colour (wikipedia doesn't tell which colour is used by SPDIF). If I get the opportunity to test a SPDIF system, I'll post the result here. Microphone has always been working perfectly. -- Realtek ALC883 speakers don't mute when headphones plugged in https://bugs.launchpad.net/bugs/253422 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
