Update to kernel 6.1.x breaks recording/streaming from HifiBerry #5709

Open rmens opened 8 months ago

rmens commented 8 months ago

Describe the bug

I have a Hifiberry DAC ADC that I use to stream audio with ffmpeg. This worked great with 2023-02-21-raspios-bullseye-arm64-lite. After doing an OS update and going from kernel 5.15.84 to kernel 6.1.0 the streaming stopped working with ALSA errors and ffmpeg can't read from the device any more. The ffmpeg version stayed the same so that's not it.

Steps to reproduce the behaviour

Device (s)

Raspberry Pi 4 Mod. B

Additional context

This is reproduced on the exact same Pi, with the exact same hardware, the exact same audio input and the exact same ffmpeg version. I could also reproduce this with another card: the HiFiBerry Digi+ I/O.

Also tried this with Ubuntu which has the same problem. Ubuntu 22.04 LTS has kernel 5.15 which works. Ubuntu 23.10 has kernel 6.1.x and has the same problem.

When installing 2023-02-21-raspios-bullseye-arm64-lite and holding back the raspberrypi-kernel package in apt but upgrading everything else, it keeps working. I'm pretty sure this is kernel related.

dcabri commented 8 months ago

Hi, I can concur and I am also seeing exactly the behaviour described above, also for kernel 6.1.21-v8+.

moodeaudio commented 8 months ago

Hi, I happen to have a DAC+ ADC and a quick test showed no issues at least on kernel 6.1.21 / Bullseye. Sometimes having a success case can help.

Pipeline iMac -> Headphone out -> [ DAC+ ADC analog in -> alsaloop -> DAC+ ADC RCA out ] -> Powered speakers.

Here's some console output.

@moodeaudio Would you mind trying to reproduce my FFmpeg example instead of an ALSA loop?

moodeaudio commented 8 months ago

Sure, no prob. Using your ffmpeg example cmd I get exact same results as you did.

As a data point the arecord command below worked fine with the DAC+ ADC and MPD was able to play the generated wav file.

pi@moode:~ $ arecord -c 2 -f S16_LE -r 48000 -t wav --duration=60 ./test.wav
Recording WAVE './test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

This suggests the ALSA plumbing is prolly ok. Bullseye ffmpeg is 4.3.6 while Bookworm includes newer version 5.1.3. Maybe this version is ok with 6.1 kernel? We are still at the beginning of Bookworm builds and so I'm not able to test much yet.

Hi, On Raspberry Pi 4 latest update/upgrade, I recompiled FFmpeg using the script provided by https://github.com/NRCHKB/nrchkb-ffmpeg-build, but adding -- ALSA module using:

# Install alsa
installalsa() {
    cd ~ || {
        echo "cd failed, aborting at alsa-lib:01"
        exit 1
    }
    echo
    echo " ---------------------------------------------------------"
    echo " |                                                       |"
    echo " |            Building/Installing alsa-lib               |"
    echo " |                                                       |"
    echo " ---------------------------------------------------------"
    echo

    wget "https://www.alsa-project.org/files/pub/lib/alsa-lib-1.2.9.tar.bz2"
    tar xjf alsa-lib-1.2.9.tar.bz2
    cd alsa-lib-1.2.9/
    ./configure --host=arm-unknown-linux-gnueabi --prefix=$PREFIX
    make
    sudo make install
    checkForError
}

After this, I get a compiled ffmpeg binary, but when I use that one, I get identical result:

Thank you for the script @dcabri. I have compiled it by hand and can confirm the issue with the latest FFmpeg on Bullseye 64-bit on a Pi 4. With the latest FFmpeg master it still only works on kernel 5.15.84 but kernel 6.1.21 gives the same error as mentioned above. So the FFmpeg version doesn't really seems to matter for this bug.

nodemand commented 7 months ago

I have a HifiBerry DAC+ ADC Pro and am using ALSA through PortAudio in my application which works with a USB sound card but cannot record nor playback anything through the HifiBerry. ALSA lists the device and aplay works. PortAudio only shows the HifiBerry after setting the environment variable PA_ALSA_PLUGHW=1. But when I select the HifiBerry as the device to use for recording and/or playback I get no sound at all! I'm on a Raspberry Pi 5 4GB running 64-bit Raspberry Pi OS Bookworm, Linux 6.1.0-rpi6-rpi-2712 aarch64.

Hoping this thread is being looked at, just making a comment because some places auto-close if there are no more comments...

nodemand commented 7 months ago

I'm not sure if this has a relation to the issue you are experiencing, but in the meanwhile my issue got fixed. I can now record and playback from and to the same device on the RPi 5 running Bookworm. Here is the solution. Perhaps the patch also works for you: https://github.com/raspberrypi/linux/issues/5747

pelwell commented 7 months ago

5747 is purely Pi 5-specific, and @dcabri is using a Pi 4.

I have to admit to being skeptical that a kernel bump would cause an issue that affected ffmpeg but not arecord (one of several reasons this hasn't received much attention yet), but that indeed appears to be the case. Starting with the February 2023 Bullseye release and rpi-updating to the most recent 6.1 kernel gives the same results using an old IQaudIO Pi-Codec+ board (which acts like a large form-factor rpi-codeczero board).

Test commands:

$ sudo alsactl restore -f Pi-Codec/Codec_Zero_StereoMIC_record_and_HP_playback.state
$ arecord --format S16_LE -c2 --rate 48000 arecord1.wav
$ ffmpeg -f alsa -channels 2 -sample_rate 48000 -hide_banner -re -y -i hw:CARD=IQaudIOCODEC ffmpeg1.wav
# Upgrade and repeat...

🙄oops. Got ya!

yes that’s why I asked so many people here to reproduce it

dcabri commented 6 months ago

Small update: ffmpeg is unable to read from the Alsa input device 'hw:CARD=sndrpihifiberry,DEV=0', however ffmpeg is able to write to the Alsa output device 'hw:CARD=C2,DEV=0'. Seems writing is easier than reading :)

bluethumb commented 5 months ago

Not that it might matter but I have a DacBerry board I try to get running on a pi400. I setup it up and I can see the card : tlvaudioCODEC and all the card's features but no control in alsamixer and no sound out But I get a lot of errors : ASoC: error at soc_component_read_no_lock on tlv320aic3x.1-0018 for register:

pelwell commented 5 months ago

Include a reasonable number of complete error messages, not just a fragment.

rmens commented 3 months ago

Just ran rpi-update, it updated the kernel to 6.6.22-v8-16k+ and that seems to solve my original issue. There wasn't much movement in this ticket, but something might have gotten changed that fixed recording/streaming from a Hifiberry via ffmpeg.

rmens commented 3 weeks ago

I apologize for my earlier conclusion; it was premature. The issue is solved when testing with kernel 6.6 on a Raspberry Pi 5, but it still persists on a Raspberry Pi 4. Could you please reopen this issue @popcornmix?
