the device to use.<br>

That it reports multi-channels LPCM indicates a bug in ALSA, myth goes<br>
by what ALSA allows: and multi-channels LPCM should never be there<br>

</div>ok.. that's good<br>
<div class="im">> StereoPCM resulted in no sound at all, but I seem to have it working now.<br>

</div>You should be using ALSA:iec958 ; with StereoPCM checked to prevent<br>
the issue of ALSA reporting incorrectly 6 channels PCM.<br>
<br>
With ALSA:default, it's likely you will not get digital audio working properly.<br></blockquote><div> </div><div>My sound system does report Dolby Digital with all 5 speakers lit up. On a stereo recording (upscaling disabled) it stays on Dolby PL with two speakers lit up.</div>
