We are using 8.1 on Xperia X Compact (F5321) and XA2 Dual (H4113) and have intermittent problems where the phones have muted microphones and no sound during calls. To get the phones back in working order we have to reboot the phones (which helps most of the times). When we look at the stream volumes on the phone we see that they are all zero: Stream volumes in dB: 0:0, 1:-6, 2:0, 3:0, 4:0, 5:0, 6:0, 7:-6, 8:-6, 9:0, 10:0, 11:0, 12:0 - phone with problems. Stream volumes in dB: 0:-7.8, 1:-11, 2:-14, 3:-22, 4:-7.5, 5:-14, 6:0, 7:-11, 8:-11, 9:0, 10:-21, 11:0, 12:0 - normal working phone. Any suggestions as to how to solve this problem would be appreciated. The problem bears some resemblance to this thread re.

I've compiled and flashed Oreo as per the instructions on a Xperia X Compact (F5321). The build goes fine and I flash the boot, recovery, system, userdata and oem (downloaded separately) without problems. When the system boots it goes past the bootloader and Sony logo, but is stuck on the Android boot animation (I've waited several hours). I've tried building and flashing both 8.0 and 8.1 as per the instructions and I get the same result for both. The device was flashed from FlashTool with the latest firmware (34.4.A.2.32) and was working fine running this.
