no cap, that's the whole job. it starts the audio client. iconic behavior honestly.

🦋 SYNOPSIS 🦋

int q6asm_run (struct audio_client *ac , uint32_t stream_id , uint32_t
flags , uint32_t msw_ts , uint32_t lsw_ts );

that's the whole signature, copy it exactly, don't come for me about the spacing, that's how it is in the source fr fr 🫶

🎀 ARGUMENTS 🎀

• ac — audio client pointer 💖 this is your main character, the handle to the thing you're starting up.

• flags — flags associated with write ✨ the lil modifier bits that ride along with the write.
• msw_ts — timestamp msw ⏱️ that's the most significant word of the timestamp, the big half.
• lsw_ts — timestamp lsw ⏱️ and this is the least significant word, the lil half. together they're the whole timestamp, we love a duo. 👑
