2016-03-04 Thread John Moulding
Hi Folks,

I've solved the problem.

Luckily, before the kernel upgrade wrecked my machine, I'd backed up the
/home directories.

After a lot of grief, I managed to install 15.10 from a flash drive
(initially, the UEFI BIOS wouldn't let me boot from the CD or the flash
drive).

Changing the kernel from 3.13.74 to 4.2.0 seems to have nailed the
problem.  I now have sound and HDMI output.

Hope someone will close this bug report, as it doesn't seem to be an
option for me..

Thanks for all the help from you guys.

John M.

[Desktop-packages] [Bug 1530142] Re: [Inspiron 5559, Realtek ALC255, Speaker, Internal] No sound at all playback write error (DMA or IRQ trouble?)

2016-02-23 Thread John Moulding
Hi Folks,

I hope there's someone out there who can help me, 'cos now I've messed
up my Linux installation.

I followed the advice above to open a ticket at bugzilla.kernel.org.
driver sound/ Alsa.  The upstream ticket number is 112721.

Advice from them was to upgrade the kernel, as the version in Ubuntu
14.04 was 'way too old'.  I didn't even know you could do that, but I
found instructions here:

https://websetnet.com/install-linux-
kernel-45-rc-3-ubuntu-1504-ubuntu-1404/

I followed the 64 bit instructions:  the download and unpack were fine,
but the update failed.  However, it did manage to mess up my PC.  I have
attached a file containing the all the lines I executed and received on
the terminal.

First, I would really like to know how to repair my 14.04 installation.

Second, does anyone have any ideas on how to safely upgrade the kernel
so that (maybe) the missing audio can be fixed.

At the moment, it boots up with multiple error messages (kernel panic,
not syncing etc. etc.), then switches itself off.  If I try powering up
again, I get 3 options:

Ubuntu
Advanced Options for Ubuntu
System Setup

If I pick  Advanced Options...  I get offered all the kernel boot
options, plus recovery versions of each.  NB the kernels include the new
4.5-rc, for which the upgrade failed.

At this point, I choose the old kernel (3.13.0-74.118-generic), Recovery
mode.

Then I get a menu offering cleanup, package repair and all sorts of
other stuff.  By this point I'm totally out of my depth.

What should I do at this point?  Is there any way to repair the
installation from the original 14.04 CD?

All help gratefully received.

John.

Hi Raymond,

you'll have to forgive my ignorance (I'm a Linux newbie), but does that
mean that I actually have to raise the ticket myself?

I've no problem with that, but I don't want to dive in and make a twerp of
myself.

Best regards,

John Moulding

Title:
  [Inspiron 5559, Realtek ALC255, Speaker, Internal] No sound at all

Status in alsa-driver package in Ubuntu:
  New

Bug description:
  No sound, either on headphones or internal speakers.  Have been all
  over forums, tried every fix I can find.  The installation is new, and
  it's on a new Dell 5559.

  Sound is not muted, and I believe the settings are correct, but it's
  hard to be sure, as each answer I find seems to have slightly
  differing advice, albeit a lot in common.

  Would be really helpful if your best and most complete FAQ answers
  were locked in one place, sorted by Ubuntu release:  otherwise there's
  no way to tell which helpful suggestions/solutions are really correct.
