Constructor Detail

AlsaCtl

public AlsaCtl(String strName,
               int nMode)
        throws Exception

Open a ctl. Objects created with this constructor have to be closed by calling close(). This is necessary to free native resources.

Parameters:

strName - The name of the sound card. For instance, "hw:0", or an identifier you gave the card ("CARD1").

nMode - Special modes for the low-level opening like SND_CTL_NONBLOCK, SND_CTL_ASYNC. Normally, set this to 0.

Throws:
