okay bestie, welcome to the snd_pcm_set_sync(9) page from the Kernel API Manual ✨ this one is short and sweet, but we are still giving it main character energy 💅

✨ NAME ✨

snd_pcm_set_sync — set the PCM sync id 🎀

🌸 SYNOPSIS 🌸

void snd_pcm_set_sync (struct snd_pcm_substream *substream );

🦋 ARGUMENTS 🦋

• substream — the pcm substream 👑 that’s the whole argument, no cap.

💖 DESCRIPTION 💖
