It will tell you if IPC is not available. In that case you have to reconfigure the kernel and include it. This kernel has to be used then with cdda2wav. For SCSI cdroms and CD-writers 2s. Cdda2wav now relies on J rg Schillings SCSI library for better portability.
Schillings scg driver is needed too.
For cdrom drives with proprietary busses under Linux 2p. The sbpcd driver is very demanded due to the lack of interrupts. The Linux pc speaker driver is limited to mono formats. Higher throughput will give better chances for non-interrupted sampling. Some kernel configurations will lead to 'out of kernel memory' errors.
