# 2.3 困ったときは…

## 2.3.1 曲の音が割れていたりして使えない!！ <a href="#id-1" id="id-1"></a>

### 2.3.1.1 バッファサイズ <a href="#id-1-1" id="id-1-1"></a>

[(see 2.2.1.1)](/user-manual/jp/2/2.md#1-1) Your buffer size may be too small, resulting in buffer underruns. To fix this, increase your buffer size. Note that this will increase latency.

### 2.3.1.2 オーディオインターフェース <a href="#id-1-2" id="id-1-2"></a>

[(see 2.2.4)](/user-manual/jp/2/2.md#4) Certain audio interface configurations don't play nice with LMMS. If you are on macOS or Windows, make sure you have SDL selected.

### 2.3.1.3 トラックの音量 <a href="#id-1-3" id="id-1-3"></a>

Your audio within LMMS may be too loud, resulting in digital clipping. This can be fixed by reducing the volume of the instruments in LMMS (either with the "VOL" knobs or through the mixer).

## 2.3.2 何も聞こえない！

### 2.3.2.1 オーディオインターフェース

[(see 2.2.4)](/user-manual/jp/2/2.md#4) Certain audio interface configurations (specifically Dummy) just don't work sometimes. If you are on macOS or Windows, make sure you have SDL selected.
