Hi all,

Seem to be having a recent problem getting 5.1 sound to work via HDMI. I am currently running Ubuntu 15.10 on an Intel NUC5i3RYH.

In short, what I am seeing is that I only seem to be...

Hi all,

I have an Intel NUC connected to my TV via HDMI, with the TV connected to a 5.1 stereo receiver via SPDIF. Until recently, this setup worked well. About a week ago, I stopped getting...

So, as an update--it definitely seems to be related to the video drivers, specifically the Intel Graphics for Linux drivers from https://01.org/linuxgraphics. I had installed these drivers from Intel...

As an update to this, I'm not sure that it's not all of the video playing in slow motion, along with the audio.

Any thoughts? I do see that some graphics drivers were updated recently through...

Hi all,

Seeing a strange problem on an Intel NUC box (NUC5i3RYH with a Broadwell i3 processor) running 15.10. Within the last day or so, all audio, whether from a video file, played from web (e.g....

Marking this solved--looks like the issue was simply the BIOS not properly failing over to the second drive. Manually forced it, then repaired the RAID array and reinstalled GRUB to sda.

Thanks!

Nevermind, I got it to work--turns out the BIOS just wasn't failing over to the second drive correctly. Did this, restored the RAID array, and reinstalled GRUB on sda.

Question--I have an mdadm-based RAID array that had a drive fail (sda). I installed a new drive, but now cannot boot at all due to what looks like a missing MBR (more at...

Thanks. Guess I should clarify a bit--the new drive is totally bare, there is nothing on it. I literally put it in the machine with the intention of formatting, partitioning, and then adding to the...

I have a home server running 10.04 configured with an mdadm-based RAID array. The boot and /home partitions are both on RAID-1 arrays, and I have a large data partition on RAID-5. There are three...

Yann,

Updated info report on pastebin: http://paste.ubuntu.com/790104/

Thanks again!

OK, I got it working--by flashing my motherboard BIOS. Not sure what was going on. I noticed some other flaky stuff going on (e.g. sometimes when rebooting I couldn't get into the BIOS to change boot...

OK, results are at the following location: http://paste.ubuntu.com/789861/

I installed to sdi7--when it booted, my three hard disks were assigned to sda (SSD), sdg (was sdb) and sdi (was sdc)....

Just tried purging and reinstalling (installed to all disks); same thing still happening. Sigh.

Here is the output of the ls:



ls -l /dev/disk/by-id/ | grep sd
lrwxrwxrwx 1 root root 9...

Running those commands does show the files--the kernel and initrd files for /boot, and the mod and cfg files for /boot/grub.

What I don't understand is why it would work with the USB key inserted,...

OK, done. Hopefully someone will be able to figure this out... It's got me baffled.

Hi all,

I recently had to reinstall Windows on my machine, which obviously took over the MBR. So I booted to a live-disk (on a USB key), then ran boot-repair to re-install Grub on all of the MBRs....

Ugh, still nothing--tried setting SDC and SDB as first boot disk in BIOS, and it still gave me the "Loading operating system... Read Error" if the USB key wasn't inserted... Sigh.

I believe it installed to all of the drives. I'm set to boot from SDA, which is my SSD first. Should this be changed?

OK done: http://paste.ubuntu.com/789290/

Thanks for the help!

Thanks. Unfortunately, that doesnt seem to be working either--booted up into Ubuntu, ejected the USB key, ran grub-install on /dev/sda (SSD drive that has my Windows install on it), ran update-grub,...

OK, I've got an interesting issue.

Just used boot-repair to fix my grub2 after re-installing Windows. Booted off a USB flash drive loaded with Ubuntu 11.10, then installed boot-repair from the...

Thank you! This was driving me nuts...

It's a bit silly that you've got to install a tool in order to change these simple settings.

This is *exactly* what I was looking for. Many thanks!
