[Bug 1582414] Re: No HDMI audio on Lenovo pro dock with T440s
The symptoms and behavior are nearly the same, so the issue seems closely related, if not the same. However, the report is for different hardware and dock (UltraDock rather than OneLink dock although both Haswell). But, without doing the back port of Dave Airlie's patches to 4.9.x, 4.10.x or 4.4.0, it's hard to know for certain. I'd suggest keeping the bug open if only to document the breadth of the problem. If I get a chance, I may try the backport myself, but I don't have time right now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1582414 Title: No HDMI audio on Lenovo pro dock with T440s To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1582414/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I tried it as well and it is still showing as unplugged. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1582414 Title: No HDMI audio on Lenovo pro dock with T440s To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1582414/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks Luke. I tried it but, sorry to report, the results are the same: pavucontrol claims that the HDMI is unplugged. I also checked with "aplay -D" commands and none of the HDMI devices detected will play. The internal audio and a USB device are detected and work fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1582414 Title: No HDMI audio on Lenovo pro dock with T440s To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1582414/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1582414] Re: No HDMI audio on Lenovo pro dock with T440s
Hello and thanks to Martin to open the Bug report and doing all the research as well thanks to the launchpad team! I got the same problem with Ubuntu 16.04 on my private and my office laptop (T440s and T440 on an ultra dock). Upgrading the dock's firmware didn't help, too. It would be nice to get a solution some time. If I can help with any data, let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1582414 Title: No HDMI audio on Lenovo pro dock with T440s To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1582414/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I also tried 14.04.2, which is kernel 3.16.0-30, and that also detected the HDMI/DP. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1582414 Title: No HDMI audio on Lenovo pro dock with T440s To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1582414/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1582414] Re: No HDMI audio on Lenovo pro dock with T440s
Thanks. Booted with the latest daily, which is kernel 4.4.0, and it does not detect HDMI/DisplayPort on the ThinkPad ultra dock. Also, from the old-releases repo, I downloaded the 14.04.1 iso running kernel 3.13.0-32, and that one DOES detect the HDMI/DisplayPort. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1582414 Title: No HDMI audio on Lenovo pro dock with T440s To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1582414/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Does this issue have to do with MST support in kernel 4.4?

Luke, do you know offhand if those sort of issues are rather due to the audio stack or the kernel? ** Changed in: pulseaudio (Ubuntu) Importance: Undecided => Low ** Changed in: pulseaudio (Ubuntu) Assignee: (unassigned) => Luke Yelavich (themuso) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1582414 Title: No HDMI audio on Lenovo pro dock with T440s To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1582414/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
