Firstly, such hardware does not always have a PCI bus, and even if it did, it is likely that the audio hardware is in the main SoC chip itself.

Check for the existance of /proc/asound. If that doesn't exist, then it is possible that the relevant audio hardware module is not loaded. Check in /lib/modules/$kernel-version to see if any sound modules are present, and try to load them.

It is common for board specific kernels to have the audio hardware driver built into the kernel, so you may not find anything, either in lsmod output, or in the modules directory.
