[PATCH] usb: gadget: u_audio: don't let userspace block driver unbind
by Alvin Šipraga 03 Mar '23

03 Mar '23

From: Alvin Šipraga <alsi(a)bang-olufsen.dk> In the unbind callback for f_uac1 and f_uac2, a call to snd_card_free() via g_audio_cleanup() will disconnect the card and then wait for all resources to be released, which happens when the refcount falls to zero. Since userspace can keep the refcount incremented by not closing the relevant file descriptor, the call to unbind may block indefinitely. This can cause a deadlock during reboot, as evidenced by the following blocked task observed on my machine: task:reboot state:D stack:0 pid:2827 ppid:569 flags:0x0000000c Call trace: __switch_to+0xc8/0x140 __schedule+0x2f0/0x7c0 schedule+0x60/0xd0 schedule_timeout+0x180/0x1d4 wait_for_completion+0x78/0x180 snd_card_free+0x90/0xa0 g_audio_cleanup+0x2c/0x64 afunc_unbind+0x28/0x60 ... kernel_restart+0x4c/0xac __do_sys_reboot+0xcc/0x1ec __arm64_sys_reboot+0x28/0x30 invoke_syscall+0x4c/0x110 ... The issue can also be observed by opening the card with arecord and then stopping the process through the shell before unbinding: # arecord -D hw:UAC2Gadget -f S32_LE -c 2 -r 48000 /dev/null Recording WAVE '/dev/null' : Signed 32 bit Little Endian, Rate 48000 Hz, Stereo ^Z[1]+ Stopped arecord -D hw:UAC2Gadget -f S32_LE -c 2 -r 48000 /dev/null # echo gadget.0 > /sys/bus/gadget/drivers/configfs-gadget/unbind (observe that the unbind command never finishes) Fix the problem by using snd_card_free_when_closed() instead, which will still disconnect the card as desired, but defer the task of freeing the resources to the core once userspace closes its file descriptor.

alsa-project/alsa-ucm-conf issue #285 was edited from Onyx47: Hello! I have the board from the title. Out of the box, the audio does not work at all under pipewire (it does, for some reason, under pulseaudio), however the following change to `alsa/ucm2/USB-Audio/USB-Audio.conf` gets the rear panel working: ``` Regex "USB((0414:a00e)|(0b05:(1996|1a(16|2[07])))|(0db0(005a|151f|1feb|419c|82c7|a073|a47c|b202|d6e7|3130)))" ``` (USB id of the card is `0db0:3130`, just added `3130` to the regex). No luck on the front panel however, tried following some discussions and figuring it out to make a complete patch on my own but it's way over my head :) Here is my `alsa-info` output: http://alsa-project.org/db/?f=22aed0d76705b354a59364e6e8e41a4fde20e4da Let me know if there is any other info I need to provide.

alsa-project/alsa-ucm-conf issue #285 was opened from Onyx47: Hello! I have the board from the title. Out of the box, the audio does not work at all, however the following change to `alsa/ucm2/USB-Audio/USB-Audio.conf` gets the rear panel working: ``` Regex "USB((0414:a00e)|(0b05:(1996|1a(16|2[07])))|(0db0(005a|151f|1feb|419c|82c7|a073|a47c|b202|d6e7|3130)))" ``` (USB id of the card is `0db0:3130`, just added `3130` to the regex). No luck on the front panel however, tried following some discussions and figuring it out to make a complete patch on my own but it's way over my head :) Here is my `alsa-info` output: http://alsa-project.org/db/?f=22aed0d76705b354a59364e6e8e41a4fde20e4da Let me know if there is any other info I need to provide.

[PATCH V2] ucm2: Rockchip: rk817: Add ALSA UCM support
by Chris Morgan 02 Mar '23

02 Mar '23

From: Chris Morgan <macromorgan(a)hotmail.com> Add ALSA-UCM support for the Rockchip RK817 audio codec. This codec is typically configured either with an internal or external amplifier as reflected by the longname. This configuration has been tested on the Anbernic RG353P (rk817_ext) and the Odroid Go Advance (rk817_int). Changes from V1: - Use a constant to control if the output mux is set to HP or SPK.

Question: is it possible to subscribe a port to system announcer ?

alsa-project/alsa-python issue #7 was opened from Houston4444: Hi. I try to add ALSA support to [Patchance](https://github.com/Houston4444/Patchance). I 'd like to create a port capable to receive events as SEQ_EVENT_PORT_START or SEQ_EVENT_PORT_EXIT in order to get a complete graph. I see in patchage source code (C++) that it uses 'snd_seq_connect_from' function to enable this events. Is it possible in python with this lib ? Thanks.
