Confirmed: Bluefin GTS 05252025 Update Fixed Mic Issues

After thorough testing, both internal microphones now work reliably after reboots:

  • Analog (ALC285): arecord -D hw:0 -f S16_LE -r 48000 -c 2
  • Digital (ACP): pw-record --target=alsa_input.pci-0000_c1_00.6.HiFi__Mic2__source

Root Cause: The 05252025 update resolved critical AMD ACP firmware and PipeWire integration issues. Minor manual tuning (sample rate/target selection) was needed for optimal performance.

Notes:

  • External microphones: Untested—focus here was on internal hardware.
  • Future improvements: Ideally, Bluefin could auto-detect optimal settings to avoid manual tuning.

Quick test for digital mic (record + play):
