AUDIO Won't work about bpi-m64-firmware

[avafinger]

Which kernel you are running? Can you update to the latest kernel?
Latest:
4d7ddeb

Try this:
a64-2GB_720p_1080p.zip

a) Use one of these DTB (attached), 720p and/or 1080p.

b) Update alsa sane values

wget https://raw.githubusercontent.com/longsleep/build-pine64-image/master/blobs/asound.state
sudo mkdir -p /var/lib/alsa
sudo mv asound.state /var/lib/alsa/asound.state

c) UnMute all you need with alsamixer
sudo alsamixer

d) reboot

PS:

• if you have trouble, remove alsa-tools and start with HDMI sound first.

later:

sudo apt-get install alsa-base alsa-utils
sudo apt-get install pulseaudio

[JimmyChangJY]

I kernel is latest one. 3.10.105.
Because the BLUE LED !! Haha ...

uname -r
3.10.105

1. I use a64-2GB_1080p.zip
2. I Update alsa sane values
3. I unMute all alsamixser
   4 reboot

When I change to analog out. I can see the volume bar up and down.
But if I change to HDMI. The volume bar won't change.
None of one come out any "noise". (Even if noise.....)

PS: I change two speakers. One is connecting with my Amazon Echo Dot now.
So the Speaker is no problem.

I have not played with Firefox sound or video since there is no HW video acceleration support for it.
Please, test with mplayer to see if you have sound output to HDMI and/or JACK, so we make sure sound is coming out.

Download some MP4 video (H264) and do:

• use your MP4, in the sample below i used big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4
• Sound output to HDMI
  mplayer-hdmi big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4
• Sound output to JACK
  mplayer-jack big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4

If you see some delay/stutter with video and sound, you should remove alsa-tools and alsa-utils, remove all sunxi_codec from modules, and start over again, first with HDMI output only, then with JACK.

With jack you should load in /etc/modules

sunxi_codec
sunxi_i2s
sunxi_sndcodec

Once you get this working you should move on to configuring Firefox

[JimmyChangJY]

Thanks avafinger.

I download some mp4 files from this website
http://www.sample-videos.com/index.php#sample-mp4-video

VLC player
HDMI work with
ALSA audio output
sndhdmi:Direct sample mixing device
Only this condition can work. If I choose other device will cause movie lag or player crash.

And I try mplayer also.
Same situation. Only one condition when you choose sndhdmi(alsa) can work smooth.

But none of one can let the AUDIO JACK work.
No matter I choose any device.

/etc/modules load in

sunxi_codec
sunxi_i2s
sunxi_sndcodec

[avafinger]

Can you please try with this dtb?

Ok, i will revisit ALSA and see if i get it right. I am experimenting with new u-boot and kernel with different DT, it may take some time.

Nothing to do with Audio JACK issue but you should run a fsck on you eMMC or/and SD CARD.

• umount the eMMC (boot from an SD CARD)
• run the fsck

sd card (in a HOST PC)

sudo umount /media/sdX
sync
sudo fsck.vfat -a /dev/sdX1
sync
sudo fsck.ext4 -f /dev/sdX2 (Fix ERRORS manually, answer YES)

for the eMMC (boot from SD CARD)

check which dev is the eMMC with:
df -lh

uMout the emmc:

sudo umount /media/ubuntu/emmcboot
sudo umount /media/ubuntu/emmcrootfs
sync
sudo fsck.vfat -a /dev/mmcblk? (where ? is your eMMC device number from df -lh)
sync
sudo fsck.ext4 -f /dev/mmcblk? (Fix ERRORS manually, answer YES)

[avafinger]

ok, testing with new kernel shows hdmi sound output and jack output works. will push to github asap.

[avafinger]

Please, try with this new kernel and new hw config. It works for me.

[JimmyChangJY]

Thanks avafinger!! 👍
Kindly remind. Don't forget the MICROPHONE!!
I want to build Amazon Alexa system on M64 ✌️

[JimmyChangJY]

How can I update the kernel and HW config??

Step 1

git clone https://github.com/avafinger/bpi-m64-firmware
cat rootfs_m64_a64_rc1.tar.gz.* > rootfs_m64_a64_rc1.tar.gz

Step2

tar -xvpzf rootfs_m64_a64_rc1.tar.gz -C ./erootfs --numeric-ow
sync
sudo umount erootfs
rm -fR erootfs

Step3

tar -xvzf boot_m64_a64_rc1.tar.gz -C ./eboot
sync
sudo umount eboot
rm -fR eboot
sync

Correct????

[avafinger]

Steps:

a) Flash a new SD CARD with latest kernel (the new u-boot has changed the order of the devices)
b) Boot it with this new SD CARD
c) Do your Step1 and Step2(use sudo in step2)

Step3 (new u-boot):

umount the boot partition:
sudo umount /dev/mmcblk1p1 (make sure boot partition from eMMC is umounted)


sudo dd if=./ub-m64-emmc.bin conv=notrunc bs=1k seek=8 of=/dev/mmcblk1
sudo mkfs.ext4 -F -b 4096 -E stride=2,stripe-width=1024 -L boot /dev/mmcblk1p1
sudo partprobe /dev/mmcblk1p1
mkdir eboot
sudo mount /dev/mmcblk1p1 eboot
sudo tar -xvzf boot_m64_a64_rc1.tar.gz -C ./eboot
sync
sudo umount eboot
rm -fR eboot
sync

[JimmyChangJY]

dd and partprobe the emmc ???
so I will lost my data? Is that nessery?
what is the step that I can keep my old data. And update the kernel only.
Because I change so many stuff, for ex., Chinese system, Chinese input, Chinese font....

BTW. why I can use firefox only? I install the chromium. But it won't work.
Thanks again avafinger

[avafinger]

We are changing partition 1 to use EXT4 (you have it as a FAT32 now) and writing new u-boot in there, that is necessary. Update kernel only won't help.

The partition 2 where rootfs resides will not be touched.
For this to work you need to boot with SD CARD with the new kernel and geometry and only then do the step3 .

You should not loose data, but you know, there is always a risk involved when it is not tested and Moore's law can hit hard. If something goes wrong with partition 1 you will not be able to boot again but rootfs will be intact and a fix will be needed.

in HOME directory and ROOT directory there is a file ./bash_history that stores all commands you typed, but if you install via Graphics (Desktop configuration) you need to redo all over again, sorry.
But is a great opportunity to document all steps, so you will master this and can perhaps publish it to help you and others.

[JimmyChangJY]

I try three days with new kernel.
ALSA with speaker out still no work.

I load the all module.
sunxi_codec
sunxi_i2s
sunxi_sndcodec

HDMI is good. I can play movie with VLC or gnone mplayer.
But the speaker out still no good.
No matter which device I choose.

Any Idea?
HW issue?

[avafinger]

Did you unMute all and increase volume?
Please refer to: https://wiki.ubuntu.com/Audio/Alsamixer

sudo alsamixer

Did you try with headphone? In my test the volume was very low on headphone.
I just think is configuration, not HW issue.
Maybe this can help a bit: http://alsa.opensrc.org/Speaker-test

[avafinger]

asound.conf is incorret, please, try with:

/etc/asound.conf

pcm.!default {
type hw
card 1
device 0
}
ctl.!default {
type hw
card 1
}

refer to: http://linux-sunxi.org/Audio_Codec

[avafinger]

FYI, in my configuration for the JACK sound output i can hear the right channel only.
I used mplayer-jack to test sound output, check if this works for you.

[JimmyChangJY]

I check everything. Over and over again.
I check asound.state in the /var/lib/alsa.
I install alsa-base alsa-utils pulseaudio
I unmute everything in the alsamixer.

I run mplayer-hdmi
Good

Then I run mplayer-jack
Still NG, only video no audio.

I try three different speakers and earphone.

linux-sunxi/libvdpau-sunxi#56

Any idea????

That was not the same issue, the video was kind of "stuttering", now you have perfect video without sound output.

But test_pages_isolated could be related to the problem. I will play the same video and see if i get same errors.

I think there is a script called m64_moniotr.sh , run this and monitor the hardware while playing video and sound.

[avafinger]

Can you please flash a fresh SD CARD (just for test) and run the same video without changing anything and see if you get something coming out from JACK? Please try with headphones also, maybe there is something with the plug.

[JimmyChangJY]

Okay, I flash two different size SD cards with new kernel.
I didn't change anything. And I try
speaker-test -Dplughw:0 -t wav -c4

And I try two speakers and two headphones. (Logitech and AKG)
Nothing come out.

BTW, HDMI audio is good.

[avafinger]

Please, check dmesg output if we can find any clue. I can't think of anything else to try.

Nothing wrong!

I can only suggest to review alsamixer configurations. Also check pcm configuration.

[avafinger]

Please, refer to the video about Jack sound output: https://youtu.be/4PtbJckmFA8
Needs a way to increase volume on alsamixer...

[JimmyChangJY]

I almost can make sure this is H/W issue.
When I use below command to test
speaker-test -Dplughw:0 -t wav -c4
I can hear very very very tiny noise from the speaker.
left speak one time and right speak one time.
That fit the test sound.
I may buy another one M64 to verify this issue.

Again the HDMI is good. So I will move on the FIREFOX and CHROME web sound issue.

Thanks avafinger.

How did you fix?

[kirantpatil]

Hi,

We faced same issue and we could hear with only 10% of clarity.

From alsamixer we enabled all options, then only we started to hear some voice.

We are looking for out of the box Microphone and Speaker to work properly.

From the forum someone ported Kernel 4.4 to M64 but it is still not available for testing.

Does Kernel 4.4 resolve this issue ?

When can we expect the updated 4.4 BSP ?

Regards,
Kiran.

[avafinger]

I have Kernel 4.4.y running on M64 but still facing some issues:

• Gigabit Ethernet with high latency and then stop working after 10 minutes or so, unusable..
• sndcodec setup seems to conflict with Gbit , i was able to work around this issue but have not tested Microphone and Speaker yet. I can't say it works properly.

My M64 belongs to the first batch that was made, you possibly need to update Wifi firmware if you want wlan0 to work properly. It works for my HW revision.

I can push an Image so you can check out the state of sndcodec and workout with alsamixer and tell the results.

[avafinger]

@kirantpatil
There is a new experimental image with kernel 4.4 you can test and check if sndcodec is working as you expected, you need to configure it from scratch, please share your results.
