I didn't see any ALSA messages in your boot log so it isn't initializing fully. A section of my bootlog is below. Have you tried it with the sound driver built in? All my testing is using the imx51_defconfig that is in your kernel tree, so the audio is built in, not as modules.
I tested with on babbage 2.5 fsl rootfs (not ubuntu) and the audio is coming up and functioning. boot messages: Advanced Linux Sound Architecture Driver Version 1.0.20. sgtl5000-i2c 1-000a: SGTL5000 revision 17 DMA Sound Buffers Allocated:UseIram=1 buf->addr=1ffef000 buf->area=de8a8000 size=24576 DMA Sound Buffers Allocated:UseIram=1 buf->addr=ac260000 buf->area=fbe03000 size=24576 asoc: SGTL5000 <-> imx-ssi-3 mapping ok mmc0: new high speed SDHC card at address 8fe4 mmcblk0: mmc0:8fe4 SU08G 7.40 GiB mmcblk0: p1 p2 ALSA device list: #0: imx-3stack (SGTL5000) -- no sound devices on babbage board with linux-image-2.6.31-100-imx51 https://bugs.launchpad.net/bugs/420447 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
