amdtp_am824_set_parameters(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… amdtp_am824_set_parameters(9) β€” from the Kernel API Manual, bestie πŸŽ€

okay so picture this: you're in the Linux kernel docs, the Kernel API Manual specifically, and you've stumbled onto this little function. it's called amdtp_am824_set_parameters, and honestly? it's giving "settings adjuster" and we're obsessed. ✨

✨ NAME ✨

amdtp_am824_set_parameters β€” set stream parameters, that's literally the whole job 🫢

🌸 SYNOPSIS 🌸

int amdtp_am824_set_parameters (struct amdtp_stream *s , unsigned int
rate , unsigned int pcm_channels , unsigned int midi_ports , bool
double_pcm_frames );

πŸ¦‹ ARGUMENTS πŸ¦‹

  • s β€” the AMDTP stream to configure. this is your main character, the thing you're setting up πŸ’…
  • rate β€” the sample rate. yes bestie, the rate. 🎡
  • pcm_channels β€” the number of PCM samples in each data block, and these get encoded as AM824 multi-bit linear audio. say that five times fast, i dare you 😭
  • midi_ports β€” the number of MIDI ports (i.e., MPX-MIDI Data Channels). MIDI girlies rise 🎹
  • double_pcm_frames β€” one data block transfers two PCM frames. that's the whole vibe of this flag, two frames, one block, slay 🌈

πŸ’– DESCRIPTION πŸ’–

so here's the tea: The parameters must be set before the stream is started, and must not be changed while the stream is running. like, no cap, do it before you hit start. once that stream is running, hands off β€” changing stuff mid-run is not the move πŸ™ˆ

⚠️ for real though: set it up first, then start. not the other way around. that's the one rule and it's non-negotiable, periodt πŸ’€
