ReSpeaker Mic Array v2.0 stops capturing


I’m using ReSpeaker Mic Array v2.0 as the audio input device of PC (Windows10).

My Windows app (c++) can get audio data from it right after booting up the app, but fails in getting them after several-minute running.

In that situation, pCaptureClient->GetNextPacketSize(&packetSize) returns 0, which means no audio data.

I’m guessing that the speaker is in a low-power (sleep) mode, so doesn’t return any audio data, but I don’t know it has sleep mode.

I couldn’t find any statement in the wiki and any related topic here.

Also, I couldn’t find any setting in the parameters list of it (written in usb_4_mic_array/, <LINK_TEXT text=“ … /”></LINK_TEXT>).

I’d like to know the details of the device.

Could someone tell me where the device’s manual is ?

Thanks in advance.

Hi there,

there is NO sleep mode for the respeaker mic array v2.0. To distinguish the hardware issue/software issue, we suggest to use audacity to record the audio from PC and see if it has the sleep issue. please make sure you have the good connection on the usb cable both sides.

For the mic array v2.0, we only have the wiki page. thanks.

Thanks for your reply.

I understand there is NO sleep mode for it. Then, the error on capturing will be brought by another thing. I’ll check on some other points, including the cable connection, you pointed out.
