You're only having playback problems, right? dma2 is for playback, I'm having playback problems, dma2 == 5 is a a 16-bit channel, and 16-bit DMA is an issue with the es18xx driver (according to the comment near the top of the file). > Can it be forced to use dma2=0 (an 8-bit channel, and the usual capture > channel on es18xx)? However, that might not be the issue anyway: I'll try a few things like dma2 == dma1, and setting dma2 to an 8-bit channel, but I think the various configuration parameters are hard-wired on the Alpha (not PnP). > This sounds very suspiciously like a difference with playing through the > native ALSA interface and the OSS emulaion.

The local version of sox (Debian 12.7.9-1) contains a library dependency on libasound.so.2, and a "strings" on the binary yields "ALSA_0.9.0rc4" as well as several ALSA error message strings. However, output by default goes to /dev/dsp (major 14, minor 3), which is definitely OSS. -- ------------------------------------------------------------------------ Bob Tracy | "I was a beta tester for dirt.
