kernel 4.19.42-v7 expired seeed-voicecard #159

emilius3m · 2019-05-18T11:40:12Z

after a kernel upgrade i have installed the kernel module following your guide but the only message that i view after the reboot is

I've got the same problem.

Daenara · 2019-05-18T14:50:55Z

Same here but I wasn't even doing a kernel upgrade. I just got my respeaker 4 yesterday and I got around to playing with it an hour ago but so far I did an hour of reinstalling the drivers, trying to set it up via snips sam tool or manually, working through old threads looking for clues (there was one that suggested a kernel revert but I tried, it did something and then didn't change anything at all.) Kinda disappointing right now because everything I read before buying one was that it will run basically without problems after installing the drivers and that snips can even set it up automatically. I hope someone figures out how to fix (or at least get around) this issue soon.

(hopeful that I get to play with my board soon)

cornim · 2019-05-18T19:14:29Z

Yep, same issue here as well. Possibly relevant lines from dmesg are:

Pillar1989 · 2019-05-19T01:33:57Z

This should be caused by kernel update 4.19, we are trying to fix it, and we will release the corresponding patch soon.

Pillar1989 · 2019-05-19T08:53:46Z

If we want to keep the kernel in version 4.14, do you accept it? In other words, as long as you use the install.sh script, the kernel rollback operation will be executed.

Daenara · 2019-05-19T11:58:48Z

Will it roll back even when the system came with a newer kernel pre-installed (because I don't know how to get it down from there)? Keeping an older kernel will be an issue in the future because other things might need a newer one but I think for now ppl will settle for a working mic array

emilius3m · 2019-05-19T12:18:22Z

if you want you can declare the product compatible only with kernel 4.14 and adopt this solution. but I don't think that in the long term it can be adopted because every future update will reinstall the latest version

cornim · 2019-05-19T13:04:01Z

Rolling back to 4.14 might work as a short term solution until you get it to work with 4.19. Keeping it at 4.14 permanently would certainly not work for me.

turmary · 2019-05-20T10:33:29Z

hi all,
In RPi Linux v4.19, the root error

[   13.640081] ac10x-codec 1-001a: prop pinctrl-0 index 0 invalid phandle
[   13.651109] ac10x-codec: probe of 1-001a failed with error -22

result in a sound card probe failing.

I think it's a bug of device tree part in RPi kernel v4.19.

thangnd85 · 2019-05-20T22:32:38Z

Temp revert kernel and kernel-headers to 4.14, then mark hold upgrade may help you. But it's not solution.

turmary · 2019-05-21T04:20:57Z

Hi all,
We tried to fix this problem by inserting overlay into /boot/config.txt instead of reverting kernel version to v4.14.
Please update code, uninstall then install again.

ABCarnage · 2019-05-21T07:45:12Z

Thanks, I saw your commit, you could have referenced it, but it's ok, I will test it.
See commit: 0ea5d2b

ABCarnage · 2019-05-21T08:30:09Z

Ok, I tested it, it works but now there is no "/etc/asound.conf" file, but I know where to find it in this repo.
Congrats @turmary
UPDATE: It works on Raspbian Pixel but not on Lite version...

cornim · 2019-05-21T18:55:11Z

Just tested in on a clean install of strech lite 4.19.
Also ran into the missing asound.conf issue but after manually copying it, everything seems to work fine.

snail59 · 2019-05-21T19:37:32Z

Hello,
I think that the /etc/asound.conf file is not missing but is deleted; at least, that is the case for me.
seeed-voicecard.service ( systemd service file) calls /usr/bin/seeed-voicecard when the system starts or reboots.
This file contains, on line 87 and 88

rm /etc/asound.conf
rm /var/lib/alsa/asound.state

So both files are deleted.
Then, it tries to guess which card is installed (mine is respeaker 2-mic)

if [ "x${is_1a}" == "x1a" ] && [ "x${is_35}" == "x" ] ; then
    echo "install 2mic"
    overlay=seeed-2mic-voicecard
    rm /etc/asound.conf
    rm /var/lib/alsa/asound.state
    echo "create 2mic asound configure file"
    ln -s /etc/voicecard/asound_2mic.conf /etc/asound.conf

    echo "create 2mic asound status file"
    ln -s /etc/voicecard/wm8960_asound.state /var/lib/alsa/asound.state
fi

where is_1a the result of this command:

is_1a=$(i2cdetect -y  1 0x1a 0x1a | grep 1a | awk '{print $2}')

I guess there is a problem with the output of the i2cdetect command :

# i2cdetect -y  1 0x1a 0x1a
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                                                 
10:                               UU                
20:                                                 
30:                                                 
40:                                                 
50:                                                 
60:                                                 
70:

I suppose that the ouptut should contain "1a" somewhere.
That is not the case so the "ln" commands are not executed, leaving the system with neither /etc/asound.conf nor /var/lib/alsa/asound.state file.

laguerreche · 2019-05-21T19:56:43Z

I ran the "./install.sh" script with the commit 0ea5d2b but my 2mic-voicecard doesn't seem to work again.

I have the /etc/asound.conf file but nor Pulseaudio neither "arecord -l" find microphones:

$ pactl list short sinks
0	alsa_output.platform-3f902000.hdmi.iec958-stereo	module-alsa-card.c	s16le 2ch 44100Hz	SUSPENDED
1	alsa_output.usb-Generic_USB2.0_Device_20130100ph0-00.analog-stereo	module-alsa-card.c	s16le 2ch 48000Hz	SUSPENDED
2	alsa_output.platform-soc_audio.analog-stereo	module-alsa-card.c	s16le 2ch 44100Hz	SUSPENDED

for arecord, I get an empty result.

The seed-voice modules seem to be loaded:

$ lsmod | grep see
snd_soc_seeed_voicecard    16384  1 snd_soc_ac108
snd_soc_simple_card_utils    16384  2 snd_soc_seeed_voicecard,snd_soc_simple_card

I get weird results with systemd when requesting status of the seed service:

$ sudo systemctl status seeed-voicecard

Finally, in the output of dmesg, I obtain the following scaring messages:

OttPeterR · 2019-05-22T01:25:08Z

I'm new to the respeaker world, I just bought the 4-mic array yesterday and tried it out with kernel 4.19.42-v7+ and it looks like I have the same issue after installing the drivers. I did run the pixel tests though so I know my device isn't broken. My system is showing everything @laguerreche post above shows.

turmary · 2019-05-22T02:43:01Z

Hi all,
I tried to fix the problem missing asound.conf.
da5f904
Please uninstall, reboot(poweroff),insert sound card, boot, install, then reboot again.

OttPeterR · 2019-05-22T20:24:35Z

That fixed it for me, thanks!

laguerreche · 2019-05-31T19:33:18Z

Sorry but that still doesn't work for me.

switch off,
I removed my card,
boot,
I uninstalled the drivers (with the uninstall script),
reboot,
I inserted the card,
reboot,
I reinstalled the drivers (with the install script),
and now /etc/asound.conf and /var/lib/alsa/asound.state don't exist.

Any idea? I have a 2mics card.

laguerreche · 2019-05-31T19:42:22Z

I am not sure that the seeed-voicecard script gets what it expects:

$ i2cdetect -y  1 0x1a 0x1a
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                                                 
10:                               UU                
20:                                                 
30:                                                 
40:                                                 
50:                                                 
60:                                                 
70:

So, no output with that: is_1a=$(i2cdetect -y 1 0x1a 0x1a | grep 1a | awk '{print $2}').

snail59 · 2019-05-31T20:41:02Z

hello,
the last commit ( git log) is da5f904, in which the test is now
is_1a=$(i2cdetect -y 1 0x1a 0x1a | egrep "(1a|UU)" | awk '{print $2}'). Notice "(1a|UU)" instead of grep 1a only.
You should maybe run git update.

By the way @turmary , egrep has been deprecated in favor of grep -E for a few years now.

laguerreche · 2019-06-02T14:03:41Z

Damn, I failed to update the git repo before running again the scripts...
Now, I'm again able to record sound.

The output of systemctl status seeed-voicecard is still strange:

However, I'm trying to use Snips but I'm facing two opposite ideas:

Snips expects a specific configuration in /etc/asound.conf, see https://docs.snips.ai/articles/raspberrypi/manual-setup,
your installation scripts overwrite the file /etc/asound.conf.

So, what am I supposed to do?

In addition, I'm also surprised to see "dmix" in /etc/asound.conf because Pulseaudio -- that I use -- was supposed to replace Dmix. Is your configuration appropriate for Pulseaudio?

Pillar1989 · 2019-06-03T01:15:49Z

Pulseaudio has not been tested
