DevKit 2: constant crackling noise in all recordings + Whisper hallucinations in silence

Hi Omi Support,

I’m using DevKit 2 and I’m experiencing a persistent audio quality issue:

1. Constant background crackling / ticking noise (“old film projector” type) is present in almost every recording.

• It’s audible when listening in Conversations and also in Offline Sync / Recordings.

• The noise is present regardless of storage mode: to phone and to SD card.

• I exported recordings and the crackling is still present when playing the file outside the app, so it seems to be in the raw audio, not only the in-app player.

2. Speech-to-text problems (Whisper): when I select Whisper for transcription, it frequently hallucinates text during complete silence. I suspect it’s triggered by the constant crackling noise.

Additional detail: the device does not boot without the SD card (so SD seems required for operation).

Could you please advise:

• Is there a known issue with DevKit 2 firmware/audio pipeline that can cause constant crackling?

• Any recommended steps (firmware update/reset/calibration) to fix raw audio quality?

• If this indicates a hardware problem, what diagnostics do you need from me (firmware version, logs, sample audio)?

I can provide:

• exported sample recordings (silence + normal speech),

• screenshots of Offline Sync settings,

• app version, iOS version, and DevKit 2 firmware version.

Thanks!
