Changelog

20210513_120hpf - PB6.47.0

• Recharacterized and retuned with EVT Bucks
  • Top: 5 samples (3 new ones + 2 from 20210323)
  • Bottom: Same 3 samples as 20210323
• Updated ReDC fallback per customer request.
  • Top: 5.471 Ohms
  • Bottom: 6.383 Ohms
• Cal and Cal+Diag bin versions remain unchanged from 20210323 as these parameters have not been modified.

20210329_120hpf - PB6.47.0

• Top speaker incorrectly had hpf as 150hz. Corrected fcutoff parameter on top speaker protect tunes.
  • All other files same as 20210323 - PB6.47.0
• Renamed package and protect tune naming convention to match accompanying 20210329_150hpf tune package.

20210323 - PB6.47.0

• Recharacterized and retuned with EVT Bucks (3 samples each Buck)
  • Bottom Speaker
    • xmax: 0.4mm
    • tmax: 120C
    • hpf: 120Hz
  • Top Speaker
    • xmax: 0.45mm
    • tmax: 130C
    • hpf: 120Hz
• Updates to firmware from 6.45.0 to 6.47.0
  • Implemented a timeout feature that allows a maximum delay between the start of the BCLK and the start of the LRCLK. If the timeout is exceeded, an error notification is sent to the driver and the command is ignored. This addresses a host-side timing issue for these signals that could lead to a no-audio situation.
  • Fixed an issue where repeated pause/resume commands could cause pops on the output.

20210319 - PB6.45.0

• Lowered tmax and xmax limits per customer request
  • Top Speaker
    • xmax: 0.4mm -> 0.3mm
    • tmax: 120C -> 110C
    • hpf: 150Hz (Unchanged)
  • Bottom Speaker
    • xmax: 0.45mm -> 0.35mm
    • tmax: 130C -> 120C
    • hpf: 150Hz (Unchanged)

20210122 - PB6.45.0

• Recompiled 20201221 tune for PB 6.45.0. No changes to tune.

20201221

• Initial Tune
