I have a probably common issue: snd-hda-intel supports my integrated hardware but I cannot get any sound from the headphones. Headphones are plugged in correct hole and this is my card's codec#0:

I have tried using hda-verb, but does not work. Commands I tried are like:

hda-verb /dev/snd/hwC1D0 0x05 set_pin_wid 0xc0
hda-verb /dev/snd/hwC1D0 0x05 set_pin_wid 0x40
hda-verb /dev/snd/hwC1D0 0x0f SET_CONNECT_SEL 1

But all without effect. When setting the pin, it doesn't change anything thus I think I cannot set a pin for the headphones node.

Also I am looking at "Headphone Playback Switch" and wondering if that is exactly what I need, but can't figure out a way to trigger it (unless it's already being triggered automatically by alsamixer, although not visible there).

Has anyone better ideas? Thanks in advance!

Use hdajackretask from alsa-tools package instead of manually using hda-verb. Do you want to get headphones on the front panel working or is this a laptop?

Thanks for the tip, that seems like a nice utility. No laptop, I am trying to get the front panel working. It's an ASROCKS motherboard

In alsamixer I can see 2 cards, the Realtek ALC892 (motherboard) and the HDA Intel HDMI. The sound is going to my LCD through the HDA Intel HDMI, S/PDIF 2 and not through the Realtek ALC892 where the front panel is.

I am sure that sound is getting to the LCD through the Haswell because if I disable all volumes on the Realtek ALC892 it can be still heard.

Thus, I am afraid this is not possible without software in the middle (pulse?) that copies the audio stream? Unless pins can be tied across cards?

NOTE: microphone can be heard back in the headphones, but no sound played

emeres · 2014-04-12 19:40:11

So how did you set up the default sound card device? Is Pulseaudio running all the time? What happens when you kill PA and run a speaker-test for the integrated card? My ALC982 copies the stream destined for front to headphone jack on the front panel out of the box, meaning the alsa driver takes care of that (I am not using PA at all).
For a manual alsa solution (if the speaker-test with default settings fails), you would need a little setup using some plugins to copy streams between cards. However PA should be also able to do this, look in its wiki.
As last resort even though autoprobe does a good job, you could try a different model for your module (ALC982 has mainly some for laptops, but similar codecs have 6stack). Or set up the headphones pin using hdajackretask.

neagix · 2014-04-13 10:01:47

I am not using PA at all, and I am not willing to.

The problem is that stream is going through ALSA to card 0 (Intel HDA Haswell) while my headphone is on card 1.

You made me think that I am already using those plugins (dmix) in my .asoundrc!

    pcm.!default {
       type plug
       slave.pcm "dmixer"
    }

    pcm.dsp0 {
        type plug
        slave.pcm "dmixer"
    }

    pcm.dmixer  {
        type dmix
        ipc_key 1024
        slave {
          pcm "hw:0,8"
          period_time 0
          period_size 1024
          buffer_size 4096
          rate 48000
       }
       bindings {
          0 0
          1 1
       }
    }

    ctl.dmixer {
       type hw
       card 0
    }

So I guess I will have to instruct dmix to make a second stream copy to another hw card...I'll give it a try

emeres · 2014-04-13 10:25:28

Using copy plugin as pcm.default and streaming to hdmi and headphones pcms should work.

Thanks, however I am a bit lost in this. Mostly because ALSA documentation does not say what is the "master" nor how to define it.

I have verified that my headphone is "hw:1,0" and my HDMI out (for sound) is "hw:0,8". So if I swap this in the pcm.dmixer I can actually route sound either to the LCD speakers or to my headphones.

However, even with my copy plugin definition below, I still do not get sound on both outputs.

ctl.!default {
	type hw           
	card 1
}

pcm.!default {
    type plug
    slave.pcm "dmixer"
}

pcm.dmixer  {
    type dmix
    ipc_key 1024
    slave {
         pcm "hw:0,8"
         period_time 0
         period_size 1024
         buffer_size 4096
         rate 48000
    }
    bindings {
       0 0
       1 1
    }
}

pcm.copyToRealTek  {
    type copy
    slave {
         pcm "hw:1,0"
         period_time 0
         period_size 1024
         buffer_size 4096
         rate 48000
    }
}

NOTE: I tried with or without bindings definition on "copyToRealtek", same result

My questions are:
1) what is my "master" that is being copied to hw:1,0? That is different from my pcm.!default, as it seems
2) how can I define such master? (wouldn't have been easier if their copy plugin had a source specification?)
3) where are the logs when the PCMs do not match and there is some warning/error? just to not make blind tests as I am doing...

Edit: now I am looking at http://de.mcbf.net/david/dotasoundrc/, looks like better than examples in official documentation

I assume, since I do not use copy myself, whatever calls pcm.copy is its master, you just specify its slaves.

period_time 0; period_size 1024

Decide between one, using both does not make sense.

And there is a dmix (pcm.dmix) running on default card (on card 0) without any further configuraion by default, which is the reason reordering modules for modprobe is a method for setting the default device.

pcm.!default { type plug; slave.pcm { type copy; slave.pcm "headphones"; slave.pcm "lcdhdmi"; } }
pcm.!headphones { type dmix; ipc_key 1001; slave.pcm "hw:1,0"; slave.rate 48000; }
pcm.!lcdhdmi { type dmix; ipc_key 1002; slave.pcm "hw:0,8"; slave.rate 48000; }

Using something like that I do not get any errors, but am unable at this moment to actually test it. I will look into it later. This ~/.asoundrc probably needs a type plug somewhere in between, because copys data format must match on input and output. However the whole copying might be more difficult than that, look here also.

Edit: I am not going to change this, but the second slave.pcm in copy plugin overwrites the first, since copy takes only one. Using plugins multi with route might be the fastest way to get this working.

That example does not work, only the latest slave.pcm is picked up (I verified this by inverting their order).

Thanks for the pointers, I am afraid I will have to use multi for this

neagix · 2014-04-13 22:15:23

The guy in 1st link had it right, this is what I am testing now:

pcm.!default {
        type plug
        slave.pcm "mout"

        ttable.0.0 1.0
        ttable.1.1 1.0
        ttable.0.2 1.0
        ttable.1.3 1.0
        ttable.2.4 1.0
        ttable.3.5 1.0
        ttable.4.6 1.0
        ttable.5.7 1.0
}

pcm.mout {
        type multi
        slaves.a.pcm "hw:0,8"
        slaves.a.channels 2
        slaves.b.pcm "hw:1,0"
        slaves.b.channels 6
        bindings.0.slave a
        bindings.0.channel 0
        bindings.1.slave a
        bindings.1.channel 1
        bindings.2.slave b
        bindings.2.channel 0
        bindings.3.slave b
        bindings.3.channel 1
        bindings.4.slave b
        bindings.4.channel 2
        bindings.5.slave b
        bindings.5.channel 3
        bindings.6.slave b
        bindings.6.channel 4
        bindings.7.slave b
        bindings.7.channel 5
}

Strangely enough, the 6 channels exist on the headphones side (Realtek) and not on the HDMI, and I cannot reduce them without screwing it up (again: no logs nor good errors reported by ALSA).

The victim of this asoundrc is dmix: I cannot play anymore with multiple applications at the same time.
This mailing list message advices to create a dmix pcm for each hardware device, then use multi on the dmix pcms. Useless to say, that didn't work.

Also I tried the .asoundrc from this thread and with proper modifications I could only get garbled noise or a segfault in libasound (!!!)

I have not yet found a solution, but PulseAudio didn't have me!

Thanks for the support
