Sony TVs experiencing HDMI audio or Dolby Vision problems now have a possible solution, though the company’s slow reaction has frustrated customers. The trouble originated from two previous firmware releases, v114.603.050.1 and v114.602.080.1, which impacted models equipped with the MediaTek Pentonic 1000 chipset. The affected lineup includes the Bravia 5, 7 II, 7, 8 II, 8, 9, 9 II, and the A95L, where owners reported audio synchronization errors, black screens, or lag when streaming via HDMI eARC.
Complaints about the problem surged in June, with discussions filling online forums like Reddit. One affected user observed that audio functioned correctly through native Android TV apps but failed when switching to HDMI-connected sources. Others described timing delays and audio cutouts, especially when using external sound systems. Sony acknowledged the issue in September, but its confirmation appeared only on the Japanese support page, leaving many to question why the company waited so long to address the matter.
The latest firmware update, v114.602.170.1, aims to correct these flaws, though initial user reports indicate it does not eliminate all problems. Some continue to encounter scan lines during Dolby Vision playback, and HDMI eARC audio dropouts remain unresolved. This update follows an earlier June patch designed to improve audio connectivity between older TVs and newer devices.

Applying the fix is simple: users need to press the Help button on their remote, select System software update, and follow the on-screen instructions. However, past updates have sometimes introduced new problems, so customers should remain vigilant after installation. Additionally, Sony is restructuring its TV Guide feature, a change that may disrupt some users’ viewing habits.
The transition from Android 12 to Android 14 appears to be a key factor in these issues. The operating system upgrade may have disrupted compatibility with certain audio and video signals, though Sony has not explained how it will prevent similar complications in future releases. For now, owners of affected models should check for updates regularly, though they may still need to exercise caution before applying them.
