Why do you think so?

L-PCM is linear PCM, which is the sample format used by practically _every_ sound card. IEC 60958 is AES/EBU, which is essentially S/PDIF, which uses linear PCM samples. IEC 61937 specifies how to transport compressed streams over S/PDIF, by pretending the data stream is a sequence of linear PCM samples.
All of this is supported by ALSA.
