[Bug 2043299] Re: Linux 6.5 breaks Novation Components web MIDI application
As mentioned above, this turns out to have been a Chrome/Chromium bug exposed by the new kernel. It has been fixed in Chrome 123, which is now the stable release.

Thank you Jonatan! I can confirm too : using Ubuntu mate 23.10 / 1.26.2. Kernel is Linux 6.5.0-21-generic x86_64 Chrome Version 122.0.6261.94 (Official Build) (64-bit) : no connection, time out Chrome Version 123.0.6312.22 (Official Build) beta (64-bit) : works just fine, circuit tracks is recognized, connected and midi works Hopefully they'll fast track the inclusion of those changes from beta to release, but in the meanwhile beta works fine so not a blocker anymore. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2043299 Title: Linux 6.5 breaks Novation Components web MIDI application To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2043299/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2043299] Re: Linux 6.5 breaks Novation Components web MIDI application
I have the same issue with other web-midi apps (for example https://teenage.engineering/apps/ep-sample-tool ) It seems this was caused by a chrome bug that surfaced with linux 6.5. See discussion here: https://issues.chromium.org/issues/40940293 There is a fix https://chromium- review.googlesource.com/c/chromium/src/+/5302886 that solved my issue with non working outgoing web-midi. I haven't tested the novation products but it seems likely that this is caused by the same bug. That fix is not yet in stable chrome.

Same behavior here, using Ubuntu mate 23.10 / 1.26.2 and google chrome (from chrome .deb, not chromium or a snap or flatpak). Kernel is Linux 6.5.0-21-generic x86_64 The circuit tracks has firmware 1.15 (latest, from dec 2022), and the following script is run before hand as root to set the midi buffers (this is required with firmwares > 1.02 with the circuit tracks as newer firmwares use bigger chunks to speed up transmissions) #! /bin/bash echo "must be run as root" echo -n "current alsa midi OUT buffer size " cat /sys/module/snd_seq_midi/parameters/output_buffer_size echo 'setting alsa midi OUT buffer to 65535' echo "65536" > /sys/module/snd_seq_midi/parameters/output_buffer_size echo -n "current alsa midi IN buffer size " cat /sys/module/snd_seq_midi/parameters/input_buffer_size echo 'setting alsa midi IN buffer to 65535' echo "65536" > /sys/module/snd_seq_midi/parameters/input_buffer_size echo -n "new alsa midi IN buffer size" cat /sys/module/snd_seq_midi/parameters/input_buffer_size echo -n "new alsa midi OUT buffer size" cat /sys/module/snd_seq_midi/parameters/output_buffer_size Using Chrome, which worked before upgrading to 23.10, the novation components website attempts to connect ( webmidi is enabled/allowed in Chrome for this device), then times out. ( When starting Components in Firefox, the device doesn't show at all, but this is not new and din't work before upgrading to 23.10 either. ) I can connect to the device using components in chrome browser on an android device, so the circuit tracks and usb cable used are working as expected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2043299 Title: Linux 6.5 breaks Novation Components web MIDI application To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2043299/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
