<title>Hardware MPEG audio codec</title>
<para>
This codec (selected by -ac hwmpa) passes through MPEG audio packets
to hardware decoders, such as the ones found in full-featured DVB cards
and DXR2 adapters.
Don't use it in combination with any other audio output device
(such as OSS and ALSA) that isn't able to decode it (you will hear
only white noise).

Digital TV transmissions (such as DVB and ATSC) and some DVDs usually have
MPEG audio streams (in particular MP2).
Some MPEG hardware decoders such as full-featured DVB cards and DXR2
adapters can natively decode this format.
<application>MPlayer</application> can be configured to relay the audio data
without decoding it.
