Youtube and sound issue in The Android-x86 7.1-r1 release

[Pietro Muscio]

Hi,

I just installed Android-x86 7.1-r1 on my mini pc alfawise x5, Intel processor x5-8350 cherry trail ( full specification at http://freaktab.com/forum/tv-player-support/intel-based-tv-players/661771-alfawise-x5-mini-pc-intel-atom-x5-z8350-2gb-ddr3-32gb-rom-gig-lan-windows-10-android-5-1 ). All works fine except youtube. The app start, load the initial page but when I stream video, a generic error is shown. I tried a youtube alternative app tubemate 2.4.3 but i had the same issue. So I tried to download a video with tubemate, the download worked great, but the video in internal video player didn't start. So I tried to view the video with MX player. The video starts but no sound.
I tried to use chrome/firefox browser with youtube site, video stream well but no sound.
Then I connected bluetooth earphones and the issue are gone: youtube app worked and sound worked. This issue is not present in the Android-x86 7.1-rc2 release.

Please, could you verify?

Thanks.

What's the output of 'cat /proc/asound/cards'?
Please try the command on both 7.1-rc2 and 7.1-r1.

Hmm, strange. This should be supported by hdmi_lpe_audio driver.
Is it loaded? Check lsmod. If not, try to manually install it:

modprobe hdmi_lpe_audio

I'll check my cherrytrail device when I go back home.

[Pietro Muscio]

Hi,

lsmod doesn't show the module  hdmi_lpe_audio loaded, so I try to load manually with the command modprobe hdmi_lpe_audio. The command run ok, module loaded, but the issue no sound remains.

Thanks.

if has /dev/snd/pcmC0D3p，then killall audioserver，audio_hw_primary will choose pcmC0D3p.

After the command modprobe hdmi_lpe_audio I don't see /dev/snd/pcmC0D3p.
I suppose there is something wrong in this version of the kernel.

The lpe_audio should be /dev/snd/pcmC0D0p

Even you see it after modprobe, it still won't work
since audio hal is not set correctly.

Maybe you can try this workaround: add
EXTMOD=hdmi_lpe_audio
to kernel cmdline.

[youling 257]

just need command “killall audioserver”，audioserver died and auto start.

alsa_amixer contents，the 'HDMI/DP,pcm=xxx Jack' is on ?

This device need the special audio hdmi hal
so just restart audioserver is not enough.
It requires the property:

setprop ro.hardware.audio.primary hdmi

Normally it should be set by init.sh.

I need to study why the driver is not auto loaded now.

[youling 257]

modprobe snd-hdmi-lpe-audio

numid=5,iface=CARD,name='HDMI/DP,pcm=0 Jack'

  ; type=BOOLEAN,access=r-------,values=1

  : values=on

mv /dev/snd/pcmC0D0p /dev/snd/1pcmC0D0p

mv /dev/snd/pcmC0D1p /dev/snd/1pcmC0D1p

killall audioserver

for me it doesnt work. i wait a fix

[youling 257]

I just give an example，make audio_hw choose current pcmCxxx，my point is needn't setprop ro.hardware.audio.primary.

of course your device different with intel compute stick(choose pcmC1D0p for 0)，but same principle. same principle on GTX1060 HDMI audio，choose pcmC1D7p for 0.

ok，step by step.

when you modprobe snd-hdmi-lpe-audio，/dev/snd only has pcmC0D0p? what files /dev/snd folder?

when you alsa_amixer contents，did you see "HDMI/DP,pcm=0 Jack" value on ?

when you killall audioserver，logcat | grep audio_hw，choose pcmC0D0p for 0 ?

[youling 257]

mistake，modprobe hdmi_lpe_audio

upstream 4.14 kernel，the module is snd-hdmi-lpe-audio.ko，Androidx86 4.9 kernel，the module is hdmi_lpe_audio.ko

[youling 257]

you needn't rename ! the intel compute stick has card0 and card1，your device only has card0 HDMI，rename back !

mv /dev/snd/1pcmC0D0p /dev/snd/pcmC0D0p

mv /dev/snd/1controlC0 /dev/snd/controlC0

killall audioserver

now how can automate this workaround at boot ?
thanks a lot

[youling 257]

this is not i want to see，i want to see when you reboot

modprobe hdmi_lpe_audio

alsa_amixer contents

killall audioserver

logcat | grep audio_hw

copy paste the result，let me see.

i use  this and  finally issue resolved. Thanks.

[youling 257]

kernel cmdline is /proc/cmdline，is the 7.1 rc2 grub.cfg "linux /Android-x86/kernel quiet root=/dev/ram0 androidboot.selinux=permissive buildvariant=userdebug"

7.1 r1 use android.cfg，do you find  "linux /Android-x86/kernel quiet root=/dev/ram0 androidboot.selinux=permissive buildvariant=userdebug" in which file?

how do you edit kernel cmdline ?

在 2018年2月11日星期日 UTC+8下午7:58:25，Pietro Muscio写道：

[youling 257]

grub2，press "e" to edit，press"c" ......

so you press "e" edit the  "linux kernel quiet root=/dev/ram0 androidboot.selinux=permissive buildvariant=userdebug"，then press "f10"，???

OK. I found the commit in kernel 4.9.80
that causes the regression and reverted it.

[Pietro Muscio]

Great news.

You can download the just released cm-x86 14.1-r1
to test.

[Pietro Muscio]

tested....sound works
