[SOLVED] HDMI audio on Current

business_kid · 02-10-2020, 11:15 AM

I can't get sound to go down the hdmi cable.
I seem to have this issue back in Slackware Current. I've had it before, I had a mega-thread in 2015 on sound, but I can't find it in a thread search. 'Aplay -l' shows me

Code:

bash-5.0$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
bash-5.0$

Now with something playing, I used to be able to open pavucontrol, select the 'Output Devices' tab, and find the HDMI in Ports, click on hdmi and sound came through the HDMI device. But now, I never see the HDMI device in pavucontrol, although aplay -l does see the card. I only get offered (joke) Speakers or headphones

How do I fix that?. BTW, lspci follows

Have you looked in alsamixer and disabled "Auto-Mute"?

That is what I had to do before selecting the output device in pavucontrol.

business_kid · 02-10-2020, 12:45 PM

Auto-mute in alsamixer? Yep. Thanks

Also tried it on a slackware huge kernel - just in case

abga · 02-10-2020, 07:54 PM

@business_kid

Please paste the outputs for the following commands:

Code:

/bin/dmesg | grep HDMI
cat /proc/asound/cards
cat /proc/asound/pcm
# pulseaudio must be running for these:
/usr/bin/pacmd list-cards
/usr/bin/pacmd list-sinks

Given your HDMI is:

Code:

card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]

- you could try forcing pulseaudio to use the HDMI output as default, by modifying your /etc/pulse/default.pa

Code:

load-module module-alsa-sink device=hw:0,3

- then bounce pulseaudio:

Code:

/usr/bin/pulseaudio -k
/usr/bin/pulseaudio -D

There's also a way to simultaneously play the sound on both analogue & HDMI outputs:
https://wiki.archlinux.org/index.php..._analog_output

You didn't detail how you got into your current issue - new (updates) pulseaudio/kernel ? If it's the kernel, maybe you need to add some options to the snd-hda-intel driver, however, that's to be considered only after you provide the outputs I asked in the beginning of the post.

aus9 · 02-11-2020, 02:12 AM

can I be rude? and point out....auto mute is a jack sense where headphones are inserted to an analog sound device
....if detected....sound is muted to analog speakers.

umm I do not wish to interfere with abga.

but if his solutions do not work....a simple .asoundrc should work but leaping ahead....some sound devices need SPDIF toggled on or off
or off on etc to enable hdmi.

Code:

 cat .asoundrc
pcm.!default {
        type hw
        card 0
        device 3
}

ctl.!default {
        type hw           
        card 0
        device 3
}

@aus9

Nothing to interfere with, I was just trying to gather more info about OPs setup/situation - helping define the problem. Any (additional) hints are welcome here. Skaendo already addressed the Auto-Mute potential cause in post #2.

business_kid · 02-11-2020, 06:24 AM

Great - 2 sound gurus here. Thanks for replies, guys.

@aus9: I think I'll leave the .asoundrc idea until I get pulse sorted (See below). Pulse piddles all over alsa configs anyhow.

@agba: Hit a problem with pulseaudio starting in system mode, so the pacmd commands gave me the middle finger. I eventually restarted with simply 'pulseaudio &' to get around it. Now your outputs:

As you no doubt noticed, there's a real issue keeping pulseaudio running. It normally respawns in Slackware. I started it again with 'pulseaudio --disallow-exit &' and that gets me going. I am getting sound through HDMI. But I really don't like changing recently updated rc files without fully understanding what I'm doing. I take it the '&' bit tells it to daemonize itself. Over to you!

BTW, I got 6 options in pavucontrol on a configuration tab not visible unless I maximise pavucontrol. But I can get hdmi sound, which is nice. I'll await your reply before marking this solved, but the answer appears to be changing the pulseaudio startup command from this

Quote:

/usr/bin/pulseaudio --system --disallow-module-loading 1> /dev/null 2> /dev/null

to this

Quote:

/usr/bin/pulseaudio --disallow-exit & 1>

EDIT: That startup config is unchanged for the last year. This worked with the original config. What's up now?

Who are they ?

If you ask me, I'm just a pulseaudio "survivor", treating pulseaudio with respect (remember? I told you that in an older thread) who learned a lot from some of the posts of the actual guru @enorbet

Well, I mentioned that pulseaudio must be running in order to be able to execute the pacmd commands.
Basically, you have two ways to run pulseaudio:
- the default/standard one, adopted by Slackware, in which pulseaudio is only executed upon request (Autospawning), thus, no need to modify your rc. init files
https://www.freedesktop.org/wiki/Sof.../User/Running/
- system wide, not really recommended, unless you have a special request/scenario for it
https://www.freedesktop.org/wiki/Sof...er/SystemWide/

Now, launching pulseaudio manually is to be done by issuing:

Code:

/usr/bin/pulseaudio -D

- it will launch and if it hits the default 20 secs - exit-idle-time (defined in /etc/pulse/daemon.conf), it will exit. Meaning, once you launch it manually, you need to hurry with the pacmd commands, or, uncomment the exit-idle-time and increase the idle to your desired time (better hurry, no need to keep pulseaudio running).
To kill it, just run:

Code:

/usr/bin/pulseaudio -k

The outputs of the commands I asked you to run show that the HDMI is activated and available. Not sure why it didn't work in the first place. If you believe that you have messed up the pulseaudio configuration - it happened to me on older versions - then, you could backup and delete the directory .config/pulse from the user's home and restart pulseaudio in order to re-create & populate it:

Code:

/usr/bin/pulseaudio -k
/usr/bin/pulseaudio -D

Obviously, the procedure should be done without X/pavucontrol running.

Sorry, only running Slackware -current on ARM (Raspberry Pi) and not using X at all. Additional, the Slackware ARM -current wasn't updated for almost a month now, drmozes seems to wait until he hits his targeted income/donations and able to prioritize it again over the podcasts.
Therefore I cannot replicate your scenario -> packages versions ...
Try removing & reinstalling pavucontrol, don't know if it helps. Maybe you have some DE issues there, some oversized buttons/fonts/etc. that are breaking the pavucontrol window.

On the startup config, already addressed it, leave it alone.

aus9 · 02-11-2020, 06:56 PM

umm I am not a PA guy....but if you continue to run PA in system mode you will have interference because in post 4 you were asked to
kill PA
restart PA in daemon mode AFAIK.

IMHO you are better off in the long run...staying with PA but copying user configs to your home dir
.config/pulse

edit the config to not autospawn PA
kill PA
make changes to whatever then just restart PA.

autospawn only effects PA if it is killed. I am not asking you to disable it on boot with your (probable) systemd setup.

hidden agenda....giggles....kill PA...never try to delete it as its a monster.....well I am joking but it pretty bad...
and use alsa .asoundrc file to play thru hdmi.

It does have 2 uses.....it is really easy to use to swap sound devices on the fly
and it easy to .....modesty forbids to reveal I think it might have a second use.

business_kid · 02-12-2020, 05:27 AM

I had all this working just dandy under alsa, sorted it for pulse, and had it working 6-9 months ago. I got into this issue because it slipped out of config sometime, and I updated it recently. I also overwrote configs fairly recently, which I hadn't done for years. I changed kernels to a home brewed one, and generally sort of brought the house down on myself a little. I thought all was sorted out, but then this showed up.

~/.config/pulse has all very recent files (Feb 10 or 11), so I'm not tempted to fiddle with that. Adding modules into the long file that is /etc/pulse/default.pa is something I looked at but didn't do. It does have
### Automatically suspend sinks/sources that become idle for too long
<stuff> and HDMI certainly fell into that category.

/etc/xdg/autostart/pulseaudio.desktop is a file in multiple languages. Once it exists, I left it alone.

I really don't understand the benefits of having pulse die off and then restart as required in --system mode. Sure, it saves a few K of ram while compromising response time. PA is a total POS imho, and has plainly failed to start up as required, like when sound was playing and pavucontrol was running. I install PA not because I want or like it, but because programs require it.

Somebody was asking me for my kernel version: 5.4.18, with the option of 5.4.14 or slackware-huge (purely while I sort this out).

At this stage, I'm sure there is a techno-ethical way to get pulse self starting; I don't have it, so I've forbidden exits, and the sky hasn't fallen in. Rule #1 in maintenance beckons: "If it works, don't fix it!"

zuriel · 02-12-2020, 06:37 AM

Code:

		off: Off (priority 0, available: unknown)
	active profile: <output:analog-stereo+input:analog-stereo>

I think this is your problem. You want the sound card on the HDMI profiles. You can change that on the configuration tab in pavucontrol. I think this line should do it from the command line:

Code:

pactl set-card-profile 0 output:hdmi-stereo+input:analog-stereo

business_kid · 02-12-2020, 01:18 PM

My optimum preference would be

Speaker/headphone sound with no HDMI plugged in
HDMI sound with HDMI plugged in, and no speaker sound.
Input - not really fussy where it comes from. This is a low-fi machine

If that command line thing does it all and I can return to Slackware's default config, no need to post but thank you and I'll try it shortly.

bassmadrigal · 02-12-2020, 04:02 PM

I'll admit I haven't read the whole thread (I am not a pulseaudio guru... I know nothing about sinks or pacmd -- I'm one of the lucky ones where it has just worked), so if this has already been discounted, please ignore. Do you happen to have any modules blacklisted? I remember a recent thread had some people disabling some module to prevent some spamming error on systems using the Nvidia driver. I think it had to do with the USB on the video card that is used for VR. If that module is also used for hdmi, it could've knocked it out and prevent pulse from using it.

I didn't know how the OP was running pulseaudio and expected the standard, autospawning mode. Instructing to kill pulseaudio in such a case (autospawning) is pretty redundant, but you never know what other app could use it (pavucontrol & co) and I just wanted to be sure it's killed and started again clean for the following instructions I presented.

@zuriel
Configuring the default profile on shell (say, putting it in /etc/rc.d/rc.local) requires pulseaudio to be running for the pactl command:

Code:

/usr/bin/pulseaudio -k
/usr/bin/pulseaudio -D
/usr/bin/pactl set-card-profile 0 output:hdmi-stereo+input:analog-stereo

A more consistent approach would be to add it in /etc/pulse/default.pa

Code:

set-card-profile 0 output:hdmi-stereo+input:analog-stereo

You could also use:

Code:

set-default-sink <name_of_sink>
set-default-source <name_of_source>
#...etc

@business_kid

Quote:

Speaker/headphone sound with no HDMI plugged in

That should be the default pulseaudio behavior, AFAIK. You could try loading the following modules in /etc/pulse/default.pa

Code:

load-module module-switch-on-port-available
load-module module-switch-on-connect

But it looks like the module-switch-on-connect module is buggy in pulseaudio 13.0:
https://gitlab.freedesktop.org/pulse...dio/issues/749

There are some other "hacks" for automation, using acpid (acpi events) or udev (udev rules):
https://unix.stackexchange.com/quest...ones-connected
https://askubuntu.com/questions/8540...-automatically

On configuring the default ouput, as suggested by @zuriel, by using the shell (and completed by me in this post), you have the alternative to use pavucontrol. Follow what @wirelessmc is describing here:

I know little about PA and what little I do know convinces me it's unnecessary alpha software, unfortunately used by programmers. I was running off the SysVinit script in Slackware
'/usr/bin/pulseaudio --system --disallow-module-loading 1 > /dev/null 2 > /dev/null'

I set up /etc/default.pa as per instructions, thank you agba; reset the original start line and it hung on rc.pulseaudio - silently, of course. So I rebooted on a live USB key, and killed PA & ran the line without the piping to /dev/null on the usb key and got myself a lecture:

Quote:

bash-5.0$ sudo pulseaudio --system
W: [pulseaudio] main.c: Running in system mode, but --disallow-exit not set.
W: [pulseaudio] main.c: Running in system mode, but --disallow-module-loading not set. # In fairness, the slackware rc script sets it.

I read that link and decided system mode was a bad idea. System mode is only for headless embedded stuff, not Desktops. So I'm marking this solved, sticking with what I've now got.
