The use of transmit and receive in this context is a little confusing, since they have different meanings depending on whether you view things from outside or inside the DMA. The confusion is made worse by the fact that the documentation (and apparently the comments as well) are wrong in the 1.0 version of the Nios II kit.

Try using ALT_DMA_TX_STREAM_ON rather than ALT_DMA_RX_STREAM_ON. That should fix your problem.
