The Fixes Included

  1. Connection Stuttering: Fixed by explicitly disabling Wi-Fi power saving (iw dev wlan0 set power_save off) whenever Bluetooth is initialized. The TrimUI Smart Pro uses a combined Wi-Fi and Bluetooth chip, and Wi-Fi power-saving sleep states frequently interrupt the Bluetooth connection.
  2. Low Audio Volume: Fixed by enabling the absolute volume (--a2dp-volume) flag for the bluealsa daemon. This stops bluealsa from forcing an artificially low software volume cap and allows your TWS earbuds to utilize their full hardware volume.

Method Origin

The method for fixing the stuttering is directly adapted from the bltMuos application fork (by nvcuong1312) built for muOS. The volume fix is derived from standard bluealsa A2DP configuration to match the out-of-the-box experience seen on muOS.

Another note: this also fixes bluetooth audio not working in game
