Running 'show config' in SRM on my Alphas (PWS500au and XP1000) reveals the settings (except possibly for mpu_port) for the ESS1888 sound chip. I recall that they are as reported in Alpha sound howtos. I hadn't been using the ESS1888 for awhile, but have just tried it out since you reported problems. I am running kernel 2.6.24.3 and Debian testing on the XP1000. I tried playing a number of wav files with alsa's aplay, sox's play and with mocp. I found that aplay and mocp worked reliably through the ESS1888. Sox's play on some files did play back a small extra segment of the file - particularly on short files and usually some section near the end of the file - once it had completed playing the file once; maybe this is what you are also observing. More onerously, my testing eventually ended in a complete system lock up! I ran play (or was it aplay - sorry can't remember now) and the system locked up. Got a response with ping across the network but couldn't log in via ssh. Have been playing mplayer through the ESS1888 for the last couple of days (don't like it though - the sound quality of the ESS1888 is not good enough for my ears) and haven't had another one of those lockups since.
