STRUCT SND_SOC_USB_DEVICE(9)

🎀 NAME 🎀

struct snd_soc_usb_device — SoC USB representation of a USB sound device.

okay bestie, this is the Kernel API Manual page for struct snd_soc_usb_device, and it's giving very "let me introduce you to the struct" energy 🫶✨

✨ SYNOPSIS ✨

Here's the whole struct, verbatim, because we do not play with code 💅:

       struct snd_soc_usb_device {
           int card_idx;
           int chip_idx;
           unsigned int *cpcm_idx;
           unsigned int *ppcm_idx;
           int num_capture;
           int num_playback;
           struct list_head list;
        };

💅 Members 💅

• int card_idx — sound card index associated with USB device. it's literally the card's index, no cap 🎀
• int chip_idx — USB sound chip array index. the chip's spot in the array, slay 💖
• unsigned int *cpcm_idx — capture PCM index array associated with USB device. yes, an index array, and yes, it's capture 🦋
• unsigned int *ppcm_idx — playback PCM index array associated with USB device. same vibe, but playback 🌸
• int num_capture — number of capture streams. literally how many capture streams there are ✨
• int num_playback — number of playback streams. the playback stream count, periodt 💜
• struct list_head list — list head for SoC USB devices. iconic little list head behavior 👑
