Bad sound quality with ReSpeaker Mic Array v2.0 #47

Open solidssss opened 3 years ago

I'm sorry but I did not know just how bad the audio output sounds with 16khz though the 3.5mm. If I had known before I bought it, I'd return it. It just sound completely awful listening to music with the respeaker. Is there someway to fix this issue?

I've flashed the firmware file 48k_1_channel_firmware_6.02dB.bin and 48k_6_channels_firmware_6.02dB.bin but there was no difference on the audio output quality. I've re-flashed multiple times.

My cat /proc/asound/ArrayUAC10/stream0 (it says 48 khz but plays 16khz sound): SEEED ReSpeaker 4 Mic Array (UAC1.0) at usb-0000:01:00.0-1.1, full speed : USB Audio
