bytcr_rt5651 - Sound does not work - Ubuntu 18.04.3 LTS

[zecamigo]

Hi!

As described here: plbossart/UCM#13
I've been having issues with the internal soundcard. It worked at some point, after some trouble shooting but it didn't last long...

pulseaudio: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="0" name="platform-bytcr_rt5651" card_name="alsa_card.platform-bytcr_rt5651" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes card_properties="module-udev-detect.discovered=1""): initialization failed.
23:46:59 kernel: Audio Port: ASoC: no backend DAIs enabled for Audio Port

Any help would be appreciated...

Thanks,

To start off, can you describe your hardware - is it some kind of laptop, and if so, it is using the Intel CherryTrail chipset?
A Brand/Model number and/or a URL will work nicely

[sundarnagarajan]

The ISO you should try is the last Bionic Beaver ISO listed on the main gape of this repo.
This is the ISO

Be cautious and do the following:

• Download SHA256SUMS.ASC.bionic
• Run gpg --verify SHA256SUMS.asc.bionic - check thet the public key matches what I have listed
• Download the ISO
• Run sha256sum -s SHA256SUMS.asc.bionic 2>/dev/null | grep -i ok

Only if all steps are OK, you should do the following:

• Write ISO to a thumb drive - I guess you know how ot do this, but if confused, there are instructions on the main page of this repo
• Boot your machine and enter BIOS / EFI and choose to boot from USB
• If there is an 'EFI USB Drivename' entry, choose that
• Choose Try Ubuntu without installing

Hope this is not overkill :)

Can you confirm your CPU is an Intel Atom X5-Z8300 ?
Of paste output of ````lshwand output oflscpu```

[sundarnagarajan]

Sorry - output of lshw and output of lscpu

That's good.
Try the ISO I linked.

At the minimum you should see the following improvements:

• All required modules should be present
• Sound card should be detected
• Sound MAY or MAY NOT work (may need UCM files?)
• Headphone jack and / or switching back and forth between headset and speakers MAY NOT work - may need UCM files
• Wifi should just work - but you probably had that working anyway
• Bluetooth should just work

And you can install from the ISO on to your hard disk - if you don't have anything of value on the hard disk, and you should continue to have all the above benefits.

HOWEVER, put off installing for a later point - just use the live session and try anything you want and get things to work.

Can't check signature, no public key...

[sundarnagarajan]

• Download the SHASUMS.asc.bionic file - assuming here that it is under ~/Downloads
• cd ~/Downloads (where SHA256SUMS.asc.bionic was downloaded)
• gpg --verify SHA256SUMS.asc.bionic
  It WILL say that the public key is not trusted - that is normal, since you have not marked my key as trusted and you SHOULD NOT

But the gpg --verify command output should say gpg: using RSA key F0C3CE69C8C00D1E4D8834F5DF2AC095857CADBD
That is the part that is key here.

Hi @sundarnagarajan again some steps seem to have got me closer to the solution

Did step 4 of the tutorial
https://help.ubuntu.com/community/SoundTroubleshootingProcedure

Unblacklisted HDMI

Copied UCMs from plbossart repo (the ones that originally worked)
sof-bytcr-rt5651
bytcr-rt5651

aplay /usr/share/sounds/alsa/Front_Center.wav
Works loud and clear!!!

But still no sound output from applications or system, just slight crackling sound every time a sound should be played.

pavucontrol GUI displays a message:

Is this just a matter of configuration? What should I be looking at?

[sundarnagarajan]

Short response - will respond in more detail later.
I BELIEVE the fact that you unblacklisted HDMI is causing pulseaudio to die. There is an issue on my github repository that talks about this, and it is why I blacklist HDMI audio - please check issues on this repository.

My conclusion SEEMS to be borne out by:

• aplay works
• Connection to pulseaudio failed

Reboot, and do following:

• Copy UCMs as you did before
• avoid the 'unblacklisting'
• Post your observations - in particular what pavucontrol shows

[sundarnagarajan]

This is the pulseaudio issue I was talking about

[sundarnagarajan]

Actually this was the original pulseaudio issue and contains more details

[sundarnagarajan]

And this is the dicsussion referenced in issue 10

[zecamigo]

Hi @sundarnagarajan

Thanks for all your patience and support! It was really helpful, I was loosing hope.

So late night yesterday I tried the following, while planning to follow your instructions today:

alsamixer > choose bytcr-rt5651 as card
went to sleep (nothing like a good night's sleep) (computer slept too)
wake up, make breakfast
wake computer

Logs errors:

10:18:13 pulseaudio: [alsa-sink-1] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

[alsa-sink-1] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_soc_sst_bytcr_rt5651'. Please report this issue to the ALSA developers.

[alsa-sink-1] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write.

10:18:02 kernel: debugfs: File 'SSP2-Codec' in directory 'Audio Port' already present!
10:06:07 wpa_supplicant: bgscan simple: Failed to enable signal strength monitoring
10:05:57 systemd-rfkill: Failed to open device rfkill2: No such device

Fixed - sound is fully operational
Ubuntu volume control settings are glitchy though. The upper right menu volume control doesn't do anything

Turn off HDMI card in pavucontrol as a precaution
Reboot

Fully fixed!
Go figure
Feel free to ask for any additional details if useful for you or curious, or just close the issue!

Again thank you a bunch!

[sundarnagarajan]

Good to hear sound is working fine now.

I took a quick look at the log lines:

• pulseaudio and alsa-sink.c errors: I have no idea - looks like this was reported in Arch linux way back in 2013. It MAY be due to default sound sink getting set explicitly in my code when the ISO boots - in which case it is harmless. If you want to explore further, you should as the UCM folks or on the alsa mailing list
• kernel: debugfs: File 'SSP2-Codec' in directory 'Audio Port' already present! - probably harmless debug error. Looks like it is fixed in this patch - may not have made it into mainline kernel?
• wpa_supplicant: bgscan simple: Failed to enable signal strength monitoring: If wifi is working fine, I would not worry about it. I can see some references to this error, but nothing conclusive.
• systemd-rfkill: Failed to open device rfkill2: No such device: If bluetooth is working fine, I would not worry about this. If bluetooth is NOT working or has intermittent problems asfet resume or after disable-enable-bluetooth cycles, open a diffferent issue

If Upper right menu volume is not working, it MAY be because pulseaudio DEFAULT audio sink is not the card you are using.

As of now (as of Ubuntu Bionic 18.04 or earlier), I don't know how to make HDMI sound work without crashing pulseaudio. It is supposed to be fixed in pulseaudio 12.0, but:

• pulseaudio 12.0 will ship with focal fossa 20.04 (not yet out)
• I have not tried to backport pulseaudio 12.0 into bionic
