# Mute a local microphone device

> How to mute or unmute a local microphone device.

To mute or unmute a local microphone device, use the [`vx_req_connector_mute_local_mic`](../../reference-manual/core/structvx__req__connector__mute__local__mic) request.

```plaintext
vx_req_connector_mute_local_mic_t* reqStruct;
vx_req_connector_mute_local_mic_create(&reqStruct);
reqStruct->connector_handle = vx_strdup(“connector handle”);
reqStruct->mute_level = 1; // 1 - mute, 0 - unmute
reqStruct->account_handle = vx_strdup(“account handle”); // OPTIONAL

int ret = vx_issue_request3((vx_req_base_t*) reqStruct);
```

The `account_handle` in this request is an optional parameter, and is similar to what is used when muting a local speaker device. This parameter specifies the account handle of the user whose microphone is to be muted or unmuted, which is the account handle that is passed in to a [`vx_req_account_anonymous_login`](../../reference-manual/core/structvx__req__account__anonymous__login). If this is left unset, then the default account handle is used. Generally, there is only one account handle, except for [couch co-op](../couch-co-op/couch-co-op-overview).
