Similar results on the 3A+ under the KMS overlay (with cma-128 to ensure it boots, re LP: #2060300); except here ffmpeg results in: [alsa @ 0xd948a930] ALSA buffer xrun [alsa @ 0xd948a930] ALSA write error: Cannot allocate memory [aost#0:0/pcm_s16le @ 0xd94c5a30] Error submitting a packet to the muxer: Input/output error [out#0/alsa @ 0xd94a5070] Error muxing a packet And the following appears in dmesg: [ 118.466695] vc4_hdmi 3f902000.hdmi: ASoC: error at soc_component_trigger on 3f902000.hdmi: -12 [ 118.468527] vc4_hdmi 3f902000.hdmi: ASoC: error at soc_component_trigger on 3f902000.hdmi: -12 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2038924 Title: No alsa sound cards on Pi 5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2038924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2038924] Re: No alsa sound cards on Pi 5
Argh, another wrinkle in this story: during ISO testing of the server images, I also tried the audio output tests with both the current setup (framebuffer driver) and the intended setup (KMS driver). The KMS driver works happily for audio output on the Pi 4 and 5. But on the 3B+, it throws the following error in mpg321: $ mpg321 -o alsa -a hw:1,0 test.mp3 ... Can't open libao driver with device hw:1,0 (is device in use?) The device isn't (to the best of my knowledge) in use, as this is directly after boot-up. Attempting output to the same device with ffmpeg results in no sound, and numerous ALSA buffer xrun reports: $ ffmpeg -i test.mp3 -f alsa default: ... [alsa @ 0xe49062f0] ALSA buffer xrun.N/A speed= 0x Last message repeated 6 times [alsa @ 0xe49062f0] ALSA buffer xrun.ed=0.743x Last message repeated 6 times [alsa @ 0xe49062f0] ALSA buffer xrun.ed=0.553x Last message repeated 1 times The content of /proc/asound/cards on the machine is: $ cat /proc/asound/cards 0 [Headphones ]: bcm2835_headpho - bcm2835 Headphones bcm2835 Headphones 1 [vc4hdmi]: vc4-hdmi - vc4-hdmi vc4-hdmi I can accept that using KMS is the way forward, and the "proper" solution to the lack of soundcards on the Pi 5. But if we go this route, we also need to avoid breaking audio output on the older platforms too. ** Changed in: linux-raspi (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2038924 Title: No alsa sound cards on Pi 5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2038924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2038924] Re: No alsa sound cards on Pi 5
I'm currently investigating switching the server images to load the kms overlay by default (they don't currently). This does appear to fix the issue, in that the vc4-hdmi ports show up in /proc/asound/cards once the overlay is loaded. Unfortunately, it also appears to break boot on the 512MB 3A+ with an out of memory kernel oops. Bizarrely, the Zero 2W (which also has 512MB of RAM) continues to boot just fine with the change, so I'm not entirely sure why the 3A+ is breaking... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2038924 Title: No alsa sound cards on Pi 5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2038924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2038924] Re: No alsa sound cards on Pi 5
Audio on Pi 5 is via hdmi, so a different driver. If that driver is not loaded, no sound cards are listed. That is expected, no? ** Changed in: linux-raspi (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2038924 Title: No alsa sound cards on Pi 5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2038924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
