Hi Po-Hsu, Unfortunately testing with a wattage meter on AC power will not work. The power saving is disabled when on AC power anyhow, it is only enabled when on battery power (and that's why we have the bug only when on battery power too). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1383997 Title: [Dell Vostro 5470] No HDMI audio with 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1383997/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1383997] Re: [Dell Vostro 5470] No HDMI audio with 14.04
Hello David, I'm not sure to what extent this tweak will affect the battery life. I tried to measure the power consumption today, with and without these two options individually. But I can't tell the real difference between them, the reading will jump within a certain range. Maybe the euipement we have here (IDRC CP-268) is not up for this job (it's being tested with adapter connected), or maybe I don't have enough knowledge for using it. Test enviroment: Laptop with battery removed, Wifi / Bluetooth turned off, backlight tuned down to the lowest level. Power comsumption (total wattage) measured by IDRC CP-268, with laptop adapter connected to it. Test result: Wattage jumps aroung 11.31 ~ 11.38 in these three secnerios. If there is any difference, it looks like it's less than 0.1 watt, but again, I'm not very confident about this. If you need a much more precise test report, I think I can imporve it by choosing a SSD laptop, with all extra modules removed. And sample the reading every 10 minute to get an average. (Or do you have any recommended testing technique or software?) Also, there is a simliar bug reported by QA before: https://bugs.launchpad.net/somerville/+bug/1067672 From here, maybe it indicates that the options snd-hda-intel power_save_controller=N could be an acceptable fix. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1383997 Title: [Dell Vostro 5470] No HDMI audio with 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1383997/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Po-Hsu, So Timo tested and confirmed the bug too. And also that using options snd-hda-intel power_save_controller=N ...in /etc/modprobe.d/alsa-base.conf also fixes the issue, and is less invasive than jackpoll_ms=500. The question is if using the above power_save_controller change causes worse battery life? If it does not, maybe we could deploy it for everyone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1383997 Title: [Dell Vostro 5470] No HDMI audio with 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1383997/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1383997] Re: [Dell Vostro 5470] No HDMI audio with 14.04
To make it more clear, I re-install 14.04.1 more than three times on this system in the past few days, it seems that when it's unplugged, the HDMI audio hot-plug detection will fail. But it work well with adapter plugged. And adding the jackpoll_ms = 500 entry, could make it work without adapter plugged. Test case: 1. Boot with AC connected, hot-plug the HDMI cable to see if the detection works 2. Unplug the HDMI cable and reboot without AC connected 3. Hot-plug the HDMI cable to see if the detection works 4. Add the jackpoll_ms = 500 entry and reboot without AC connected 5. Hot-plug the HDMI cable to see if the detection works Actual result: * HDMI audio detection works with step 1, but it won't be detected on step 3. After the new entry was added, detection works on step 5.

I would say let's ignore comment #6, I can't reproduce it anymore, sorry for the confusion. I tried to install 14.04.1 + 3.13.0-37 kernel to reproduce it, but the speaker audio output changed to Dummy Output, which is totally different from the environment in the beginning of this report.

Warning: rate is not accurate (requested = 11025Hz, got = 32000Hz) please, try the plug plugin This is nothing to worry about. The hardware does not support 11025Hz, and the string -D hdmi:HDMI,1 does not allow alsa to insert any sample rate converter. And after adding the new entry to /etc/modprobe.d/alsa-base.conf, the HDMI output option in Sound Settings won't be available even you play the wav file with the aplay command. So what you're saying is that adding jackpoll_ms = 500 actually makes things worse? That's very surprising. If the device show up when you do things with it (such as aplay) that indicates a power management problem, i e, the device does not wake up on plug/unplug. And jackpoll_ms = 500 should keep the power on all the time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1383997 Title: [Dell Vostro 5470] No HDMI audio with 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1383997/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1383997] Re: [Dell Vostro 5470] No HDMI audio with 14.04
I would say it's quite unstable, and I was informed that this could be a kernel race issue. After I installed the 3.12 kernel on this system and cold boot into 3.13.0-37 (I forgot to switch to 3.12 on boot) with HDMI cable connected HDMI audio is now available. But if you disconnect it, sometimes it won't disappear automatically from Sound settings. If it's gone, hot-plug can't make the HDMI audio output available again.
