Optial Audio not working

I for the life of me cant get any audio through my optical link. spdif shows muted in alsmixer but i cant unmmute it.

Any experts out there to help?

Heres my alsa-info
http://www.alsa-project.org/db/?f=e5...40d97ba29daa8b

Thanks.

You have pulseaudio running

open pavucontrol click on config tab and select IE958 (=spdif)

if that fails run

alsamixer -c0

right arrow to spdif and press the m button to mute or unmute

what does the -c0 switch do? I did find a little earlier that if i go into alsamixer and press m it would unmute it. actually i pulled up alsamixer then F6 to select 0 HDA Nvidia then i was able to arrow over to m the spdif. Have to do this every time i log in.

pavucontrol doesn't even have an option to select IE959

EASY SOLUTION first

Quote:

Have to do this every time i log in.

if spdif is having to be manually turned on each boot, the easy solution is to turn it on manually like you now know then run this command

Code:

sudo alsactl store

reboot to test your optical now ok

if not read on

#####################
If that fails for any reason----
ahh it sounds like (no pun) that you want something else grabbing index=0 or card 0

pls upload a snapshot of your terminal running these commands and link to them
---I use a file sharing site called tinypic.com

Code:

alsamixer -c0

alsamixer -c1

alternatively run alsamixer then take a snapshot of results of you pressing F6,
you can use mtpaint---pulldown file----actions----time delayed shot
---minimise mtpaint
click into terminal press F6
wait

then grab just the F6 window in mtpaint save it as a jpeg or png and you can attach it----rather than link to it if you prefer

2) Fedora

does that have a /etc/modprobe.d/alsa-base.conf?

look into each file and tell me the file names that have lines that start

options blah blah

we may use this file or alternatively we may use a home folder file .asoundrc

post the contents to this command pls

and advise if you have a /etc/asoundrc or /home/yourname/.asoundrc

Code:

cat /proc/asound/pcm

aplay -L

3) can you take a snapshot of your pavucontrol config tab pulldown
---I am surprised alsamixer can see your spdif but PA can't

I mis-spelt your spdif earlier, your text file shows its IEC958

cheers

My system doesnt have that. theres only one file there names openfwwf.conf

3) can you take a snapshot of your pavucontrol config tab pulldown
---I am surprised alsamixer can see your spdif but PA can't

https://www.dropbox.com/s/ttgp196n7en53d8/pau.png

hmmm no spdif showing up in aplay -L either

2) Just to be sure, when I posted about hdmi, were you wanting hdmi output or do you truly have an optical cable plugged into the little round hole?

3) If hmdi you can see in your pavucontrol that you can choose hdmi output but have not clicked it
second one or third depending on whether you want both

4) if spdif, this image
https://www.dropbox.com/s/2w26n4k9oljqzy2/c0.png
does not show spdif so you may need a model=string

5) ok relooking at your alsa-project link first post for spdif we see

Quote:

control.27 {
iface MIXER
name 'IEC958 Playback Switch'
value false

6) pls copy and paste this exact command into a terminal as local user
copy and paste exact results of output
tell me if alsamixer shows up spdif, if so what is its status ---muted or unmuted?

Code:

amixer -c0 cset iface=MIXER,name="IEC958 Default PCM Playback Switch" 1

7) but of course your controls may differ from mine so thats me leaping ahead in (6) pls post the results of these commands so we get a better idea
-----if you don't want hdmi but spdif---OK

Code:

amixer contents

amixer scontrols

amixer controls

good luck

oh I editted earlier post

did you try the alsactl command now showing at top of reply 4?

EDIT

if the playback switch now shows spdif in alsamixer then unmute it
and then redo the alsactl store command

----and hopefully post is solved?

I truly have an optical cable plugged in.

I did unmute it and tried running that command. rebooted and its still muted at log in.

Quote:

excellent progress so now
https://www.dropbox.com/s/1wsaylynm04ym77/c0_again.png

pls unmute the first spdif and the second which will read as spdif (default) as unmutetd but next
I want you to disable "auto mute'

ie I want all spdif(s) showing as green = unmuted

next time I will ask for a alsamixer -Vall, but we live and learn ;)

Next I need you to store those settings

Code:

sudo alsactl store

pls full reboot and report what your alsamixer looks like for
spdif spdif default and auto mute----no need for image at this stage

If of course we have a winner say so as well.

EDIT

hmm hang on

report if spdif only appears in command
alsamixer -Vcapture and not in
alsamixer -Vplayback

you may still have an issue....it should show up in playback (outback device)

Quote:

SPDIF was muted after reboot. Auto-Mute was disable.

Quote:

report if spdif only appears in command
alsamixer -Vcapture

no spdif here.

ok thats weird we will look at a dirty work-a-round as I want your spdif to be unmuted on reboot

I assume you have a /etc/rc.local?

can you post its contents pls?

2) do you have a folder called /usr/share/alsa/cards which contains HDA-Intel.conf
search for it pls if not there try

Code:

sudo find / -name HDA-Intel.conf

when found post its contents

3) but on reboot I want to know what spdif status is pls

just run alsamixer and report each spdif

4) then before reboot, time to try a home folder file copy and paste this pls...at your home folder

Code:

echo "pcm.!default {

type hw

card 0

device 3

} 

" > .asoundrc

logout and login back in

recheck alsamixer for spdif and report pls

trivia

I should say a few things so you know I am just as disappointed in our results so far

1) your codec does not appear in here
https://www.kernel.org/doc/Documenta...dio-Models.txt

that means I can't use a model=string technique

2) all of your amixer commands I asked for ----were very deficient compared to mine eg

3) when we enabled the spdif playback switch and you adjusted your mixer settings
saved those settings with sudo alsactl store
----reboot is supposed to work

end of trivia

so now we try a asoundrc but as they may fail, I am leaning towards a series of
amixer commmands in rc.local

ok on each reboot can you also save the contents of this command results pls
post it if its the same, obviously if spdif is unmutetd just say so

Code:

amixer get IEC958

the command I like to put into rc.local is the second one but I show both bits of mine to show the change

Code:

 amixer get IEC958

Simple mixer control 'IEC958',0

  Capabilities: pswitch pswitch-joined

  Playback channels: Mono

  Mono: Playback [off]

gordon@box:~$ amixer set IEC958 unmute

Simple mixer control 'IEC958',0

  Capabilities: pswitch pswitch-joined

  Playback channels: Mono

  Mono: Playback [on]

see how playback is now on?

I do have it.

4) then before reboot, time to try a home folder file copy and paste this pls...at your home folder

Do i name the file .asoundrc ?

Hi

now ignore all my waffle about asoundrc......I am more interested in making a simple /etc/rc.local

Firstly I found this
http://docs.fedoraproject.org/en-US/..._Sysadmin.html

Quote:

3.2.4. rc.local no longer packaged
The /etc/rc.d/rc.local local customization script is no longer included by default. Administrators who need this functionality merely have to create this file, make it executable, and it will run on boot.
Upgrades are not affected by this change.

ok first I need to know the full pathway to your amixer command, likely to be /usr/bin/amixer but YMMV

Code:

sudo find / -name amixer

lets pretend its the same as mine---but changes my command if you have different pathway pls

2) we will create your file /etc/rc.local contents in the next lot of commands

but it looks Fedora uses systemd as per
http://forums.fedoraforum.org/showthread.php?t=269859 ---see reply 11

Note I use an init.d system so know zip about systemd

but it also appears systemd does not need an /etc/rc5.d/rc.local with a sym link but your report will matter

pls copy and paste as is,

Code:

sudo su

echo "#!/bin/sh 

/usr/bin/amixer set IEC958 unmute



exit 0

" > /etc/rc.local



chmod 755 /etc/rc.local

chown root:root /etc/rc.local

cat /etc/rc.local

last command should look like this

Quote:

#!/bin/sh
/usr/bin/amixer set IEC958 unmute

exit 0

full reboot

check is spdif is unmuted and you have digital sound pls

pls report any issues
