Do you mean the Philips HTS3548? Let me take another look at the LIRC config files, I didn't put as much effort into coding up audio devices as I did TVs when I was working on Philips.

For now, support for new devices in Pierogi is pretty much done through me. The LIRC project, however, has been built up by hundreds (maybe thousands) of IR enthusiasts creating software to read the IR pulses sent by remotes into their PCs. It's really a kind of amazing project...
