I got the kernel recompiled with disabled DMA and installed it. Sound now works fine.
For anyone else wanting to do this I followed Roberts notes and used a couple other pages to help with figuring out some details such as installing things needed for the cross compile on a Ubuntu PC: http://elinux.org/Building_BBB_Kernel http://wiki.beyondlogic.org/index.php/BeagleBoneBlack_Building_Kernel I didn't mess with TFTP as both those pages show. After the cross compile I transferred the new kernel file to the BBB with Filezilla (after I backed up the system in case of trouble) and installed with dpkg -i ... as Robert suggested.
