intel hdmi audio + intel onboard audio + usb audio

[hatharry]

i have found a way to to get all of my audio working on my brix pro.

the order is usb audio, onboard audio then hdmi audio (disable onboard in bios for hdmi audio).

i had to patch the kernel and add kernel parameters:

add the below code to the linux line of your menu.lst or grub.cfg:

snd_usb_audio.index=0 snd_hda_intel.index=2,1

if you can not disable onboard but want to use hdmi change: snd_hda_intel.index=2,1  to  snd_hda_intel.index=1,2

and apply the patch attached

Hi,
thank you for your patch, I have Intel HD on my PC, Audio not working on my HDMI port in Android x86 4.4.4.
who can I use your patch for fixing this Audio problem?? I have Disable option for HD Audio in BIOS, Who can use your patch.
sorry I'm beginner !

[hatharry]

Download a live linux eg linux mint, ubuntu etc...

Boot into linux

Replace the kernel with this kernel

Add the lines above to menu.lst

[Ali Razavi]

thank you,
I search all my device for menu.lst and grub.cfg but not found! I use file manager and this command in terminal emulator: find / -type f -name "grub.cfg" and find / -type f -name "menu.lst"

[hatharry]

up to date kernel

you will not find menu.lst in android. you will need to boot a live version of linux from usb or cd.

[Ali Razavi]

after boot by Ubuntu and copy the new files and edit menu.lst android don't boot, I have to back my original files to boot android again !!!

[hatharry]

Lets make this easier. Please just replace this file.

[Ali Razavi]

thanks again,
I just copy that file to /system/lib/modules/3.18.0-android-x86+/kernel/sound/pci/hda/ and rename the my old file to snd-hda-codec.ko.old. After reboot android, sound not working. not at HDMI port not at audio out port.
please check my menu.lst file, this is correct ?!

thank you again

[hatharry]

menu.lst is not correct . it should be:

kernel /android-4.4-r2/kernel quiet root=/dev/ram0 androidboot.hardware=android_x86 SRC=/android-4.4-r2 snd_usb_audio.index=0 snd_hda_intel.index=2,1

can you also run in android

sudo alsa_aplay -l

that should give the order

[Ali Razavi]

I changed the menu.lst in correct format, but when reboot android sound not work.
when I run "sudo alsa_aplay -l" in terminal the output is: aplay: device_list: 241: no soundcards found...

[hatharry]

try:

su

alsa_aplay -l

[Ali Razavi]

the result is same: aplay: device_list: 241: no soundcards found...
I think menu.lst file is not correct for me, because when I recover the original snd-hda-codec.ko file again sound not work.
I just need HDMI sound, I haven't USB sound card.

[hatharry]

Does sound work in ubuntu? Put the menu.lst back to normal and enable onboard sound and check Alsa_aplay again. Doesnt look like any devices are found.

[Ali Razavi]

HDMI sound and normal outpot sound in Ubuntu Live working good.  When I put menu.lst in normal mode and enable onboard sound in bios, the "alsa_aplay -l" output is: aplay: device_list: 241: no soundcards found...

[hatharry]

Looks like you are not using superuser. Please make sure terminal is granted access.

First command should be: su

You should see #

Then enter alsa-aplay

[Ali Razavi]

I use SU and run command in Super User mode.

when I recover the original KO file and reboot the android the output of alsa-play -l is:
root@x86:/ # alsa_aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC662 rev3 Analog [ALC662 rev3 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

but whit your KO file the output is:

aplay: device_list: 241: no soundcards found...

thanks

[hatharry]

thanks for testing.

use this kernel and disable onboard sound

Hi hatharry,
Thank you for the patch.
However, it seems to be a dirty hack that
I'm reluctant to merge it to the codebase.

I think the correct way to support HDMI audio
is to create an audio HAL (audio.hdmi.xxx.so)
for it. The audio_policy.conf is probably needed
to be modified as well.
This is the way that most android tablets do
I've seen.

[hatharry]

I also agree with you. I will try find some examples so we can make it work without dirty hacks

[hatharry]

Am i right in saying this code in audio_hw.c:

static int select_card(int d)
{
    int i;
    char dname[32];
    for (i = 0; i < 3; ++i) {
        sprintf(dname, "/dev/snd/pcmC%dD0%c", i, (d == PCM_IN) ? 'c' : 'p');
        if (!access(dname, R_OK | W_OK)) {
            ALOGD("found %s %s", (d == PCM_IN) ? "in" : "out", dname);
            return i;
        }
    }
    ALOGE("no pcm card found!");
    return -1;
}

is looking for pcmC0D0p, but hdmi device start at pcmC0D3p?

[Ali Razavi]

Can I run a script on terminal for switch default sound to HDMI ???

[Ali Razavi]

Unfortunately after replace the kernel files, android does not boot again :( and I miss the old files.
I want install a new android x86, please help me what version I must install for best performance and stable????
thanks

The Kitkat branch is the most stable

Hello

I have a gigabyte brix too but mine is model bxbt-1900 (baytrail)

the device order I got when I use the alsa_aplay -l command is analog=0 HDMI=3 no USB or digital, also if I disable onboard audio from BIOS the same command says there's no audio hardware so I can't disable it. What do I have to change to use your patch? I'll be very grateful if you help me

[Luke McIntyre]

You need to apply the kernel patch and re-compile. Hdmi will then be at device 0

Does it trick works on ATI video adapter?

[Jason Pereira]

Hi Luke,

I am a newbie. Could you please give me the steps on how to patch the kernel and add kernel parameter.

Thank you,

[Luke]

have you downloaded the source? that would be a good start.

[Francesco Mirizzi]

Hi,
I've a bay trail pentium j2900, I've no audio trough hdmi, can you help me how can I solve this problem?
What android-x86 have to install? I've also install same patch?
Thank you advise.

[Luke]

Download the kitkat source then apply the patch to the kernel.

[Francesco Mirizzi]

I'm newbie, can you help me to find same tutorial to apply patch and compile a kernel?
Is there any way to apply the same patch to android 6?
Thank you advise

I recently installed Manjaro Linux on my computer (any Linux distro should work, right?). Using the "locate" command ("locate audio.hdmi"), I couldn't find any files named "audio.hdmi.*.so". So, my next step was to do "locate audio | grep hdmi", and I found a compressed file called "snd-hdmi-lpe-audio.ko.xz" in my kernel modules folder. The compressed file contained one file, which I extracted and stored on my Google Drive. Here's a link to the file in question. Let me know what you make of it.
