[Desktop-packages] [Bug 1672822] Re: sound only coming from left speaker on acer predator (fresh install)

[Carlos Velasco]

left, if i remove the two little ones (L & R), the subwoofer can sound)

I run "sudo lshw" so the text is long:

  Looking around online there seem to be a lot of problems with acer
  predator laptops and sound on ubuntu.

  subwoofer seemed to be working and altering the file only the left
  speaker was working. On ubuntu 17.04 only the left speaker was working
  regardless of how I altered the above file.

  
  Note that the speakers work perfectly fine on windows 10. 

  Looking around online there seem to be a lot of problems with acer
  predator laptops and sound on ubuntu.

[Desktop-packages] [Bug 1672822] Re: sound only coming from left speaker on acer predator (fresh install)

[matthew p]

This is still an issue for my hardware. The workaround in the comments
does seem to work, but honestly it took finally googling the right
phrase after months of trying to find a solution on and off.

If this bug could actually be fixed by reopening it, I would like to see
it reopened because it might help other people out that aren't as lucky
as the people that find this bug ticket.

[Desktop-packages] [Bug 1672822] Re: sound only coming from left speaker on acer predator (fresh install)

[CleverSageLife]

@rotten hdajackretask worked for me.  Confirmed.

My Acer Predator 15 G9-593-72VT has:
Card: HDA Intel PCH
Chip: Realtek ALC255


FIXING IT BY SETTING THE PINS AKA JACK RETASKING:


STEP 1: INSTALL THE FOLLOWING SUITE OF APPS:
sudo apt-get install alsa-tools-gui

STEP 2: RUN THIS PARTICULAR APP FROM THE SUITE AT THE TERMINAL:
hdajackretask

STEP 3: CHECK THE FOLLOWING BOX:
show unconnected pins

STEP 4: SET THE PINS AS FOLLOWS: 
0x14 to "Internal Speaker" (do NOT check the box for override)
0x17 to "Internal Speaker LFE" (check the box for override)
0x1b to "Internal Speaker (Back)" (check the box for override)

STEP 5: TEST IT 
(play a song or stream a video?)


STEP 6: IF THE TEST SUCCEEDS, CLICK BUTTON:
Install Boot Override
(you will need to put in an admin password)

STEP 7: REBOOT
See if the settings stuck after a restart.

At any time, if something goes wonky, restart the computer, and try
again. I found that sometimes the sound quits and freezes while applying
different configs, but a restart resets it back to normal.

[rotten]

I found a work-around here:
https://ubuntuforums.org/showthread.php?t=2357875

Using hdajackretask:

I set pin 0x14 to "Internal Speaker"
  0x17 to "Internal Speaker LFE"
  0x1b to "Internal Speaker (Back)"

The laptop sounds _much_ better now.

[Desktop-packages] [Bug 1672822] Re: sound only coming from left speaker on acer predator (fresh install)

[rotten]

I have a brand new Acer Predator 17x and I just installed Ubuntu 18.04.
I also only get sound out of the left speaker. When I do the sound test,
both the Right and Left channel sounds come out of the left speaker.
This laptop actually has a subwoofer as well as a right speaker.
Neither the right speaker nor the subwoofer working.  With Windows it
sounds pretty good.  Under Linux is sort of sounds like my cell phone.

If I can help in some way, let me know.

  fedora F25-WORK-x86_64-20170228 via live usb

  Device: acer predator: G9-593-7757 15,6"/i7-7700/32 GB RAM/512 GB

[Desktop-packages] [Bug 1672822] Re: sound only coming from left speaker on acer predator (fresh install)

[Dahna]

Btw it might sounds not serious but in fact on my laptop it's
essentially make sound system useless - sound from subwoofer comes very
distorted making almost impossible to distinguish any voice, so no
skype, no movies, no youtube or podcast on ubuntu.

Have to boot to windows only for that

>From googling I would say it affect multiple laptops with more than 2
speakers, not only acer predators

  ; rlimit-rttime = 20

  ; default-sample-format = s16le
  ; default-sample-rate = 44100
  ; alternate-sample-rate = 48000
  default-sample-channels = 3
  default-channel-map = front-left,front-right,lfe

  ; default-fragments = 4
  ; default-fragment-size-msec = 25

  ; enable-deferred-volume = yes
  deferred-volume-safety-margin-usec = 1
  ; deferred-volume-extra-delay-usec = 0

  but this did not work. I also tried various other permutations to see
  if changing the order of  front-left,front-right,lfe would work but it
  did not. I also tried to see if it would work in fedora but the same
  problem occurred there. When on ubuntu 16.10 at first only the
  subwoofer seemed to be working and altering the file only the left
  speaker was working. On ubuntu 17.04 only the left speaker was working
  regardless of how I altered the above file.

  
  Note that the speakers work perfectly fine on windows 10. 

  Looking around online there seem to be a lot of problems with acer
  predator laptops and sound on ubuntu.
