In windows you are able to put it in analog surround sound mode - that is you have 3 3.5mm jacks running as output with 2 channels each. I am trying to replicate this behaviour so I can use the card as a 6 channel output device with jack audio and ardour (my setup works in stereo mode - now if i could just get the card to show 6 channels instead of just 2 - heck even 4 channels would be an improvement) What do I need to do to make this work? relevant sound routing: soundcard &gt; alsa &gt; jack &gt; aurdour &lt; pulse (I basically route all my sound through aurdor for effects processing - then out to the soundcard) I'm running on Fedora 18 Dell XPS 17 L702x i7 2670qm 16GB ram 265GB ssd # lspci -nn 00:00.0 Host bridge [0600]: Intel Corporation 2nd Generation Core Processor Family DRAM Controller [8086:0104] (rev 09) 00:01.0 PCI bridge [0604]: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Po</pre> Kronos 2013-04-27T18:32:16 http://comments.gmane.org/gmane.linux.sound/1737 <pre>Classic Wii Remotes provide a speaker on the device. We can stream PCM data, mute and change volume via special protocol requests and remote audio registers. The device supports several different formats, but fully understood are only signed 8-bit PCM and something that looks like 4-bit Yamaha ADPCM. Theoretically, we can set data-rates from 183Hz up to 12MHz, but a realistic range for Bluetooth l2cap is 1500-4000 Hz. Data is streamed as 20bytes blocks and must be sent in a constant rate. There is no way to read the current position. It would be way too slow, anyway.

This is due to the TX FIFOs are empty, and this request line is active all the time, when the CCSR_SSI_SIER_TDMAE bit is set. In this case also the TX FIFO underrun interrupt will flood the system forever. To ensure the first edge happens after enabling the TX side of the SSI unit and to trigger the SDMA unit successfully enable the CCSR_SSI_SIER_TDMAE on demand only. To be sure, this patch does the same for the CCSR_SSI_SIER_RDMAE (RX side) bit.
