Still, something is telling us that there is an internal speaker, so please submit alsa-info ( <a href="https://wiki.ubuntu.com/Audio/AlsaInfo">https://wiki.ubuntu.com/Audio/AlsaInfo</a> ) so we know for sure what it is. Second, if this is a motherboard that has a "internal speaker" header on it which you chose not to connect when you built your HTPC, you should configure the system accordingly, e g by disabling the internal speaker through hda-jack-retask. If there is not such a header, then you likely have a bug in BIOS, which we can work around in the Linux kernel. > The video and audio goes out from the motherboard through HDMI > to a monitor that has its own speakers that work perfectly through the HDMI > connector.

The "corner case" refers to your phantom internal speaker.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
