</div>Does it work with two channels? Do you use DMA or FIQ? Could you try the<br>
other variant? <br></blockquote><div><br> Unfortunately, I can't test it using two channels because our board has a wm8974 mono codec. Please could you point me how can I change between FIQ and DMA? I thought FIQ was only for AC97,<br>

It helped me a lot during development to use a tool like memedit<br>
(<a href="http://www.pengutronix.de/software/memedit/index_en.html" target="_blank">http://www.pengutronix.de/software/memedit/index_en.html</a>) to show a<br>
register dump of the SSI/Audmux units of a working setup and a non<br>
working setup. Usually the differences showed quite fast why one was<br>
working and the other was not.<br></blockquote><div><br> Indeed, this will be my next step.<br><br> Thank you for the tip. <br></div></div><br clear="all"><br>-- <br>Javier Martin<br>Vista Silicon S.L.<br>CDTUC - FASE C - Oficina S-345<br>
