💅 snd_soc_usb_disconnect — bestie's guide to the Kernel API Manual ✨

okay so picture this: you're deep in the kernel, the manual you're reading is literally called Kernel API Manual, and the whole page is about one (1) function. her name is snd_soc_usb_disconnect, and she's here to tell everyone that a USB device just... left. 🫶

🎀 NAME 🎀

snd_soc_usb_disconnect — the notification that a USB device has disconnected, aka the group-chat "she's gone" message but for audio hardware 😭

✨ SYNOPSIS ✨

int snd_soc_usb_disconnect (struct device *usbdev , struct
       snd_soc_usb_device *sdev );

like, she takes two pointers and returns an int. no cap, that's the whole signature 💅

🌸 ARGUMENTS 🌸

  • usbdev — the USB bus device. your main character, the actual USB thing on the bus 🦋
  • sdev — the USB SND device to remove. yes bestie, she's getting removed. it's giving cleanup era 🧹

💖 DESCRIPTION 💖

so basically: this is the heads-up call. snd_soc_usb_disconnect notifies that a new USB SND device disconnection happened, and it passes that news along to the USB backend. that's it, that's the vibe — a little "hey, this device is out" memo to the backend, and she slays it 🔥

ngl, it's a notification function, so think of it as the ✨ polite heads-up ✨ before things get torn down.

👑 SEE ALSO 👑

the kernel file lives at ./sound/soc/soc-usb.c, and honestly the whole friend group is iconic:

and that's the whole page, bestie 🌈 this one came from ./sound/soc, dated October 2026, and she's filed as snd_soc_usb_disconnect(9) — periodt 💜✨
