Hi, out of curiosity I connected some active PC speakers to my SS5, but so far, I was not yet successful to play something good.
I made some minimal tests using an au file downloaded from here: http://www-mmsp.ece.mcgill.ca/documents/AudioFormats/AU/Samples/AFsp/M1F1-int8-AFsp.au playing this on i386 sounds good: (audioctl -f /dev/audioctl play.channels=2; audioctl play.precision=8;audioctl play.rate=8000; audioctl play.sample_rate=8000; cat M1F1-int8-AFsp.au) > /dev/audio0 but doing the same on the SS5, I get some very noisy output. Don't know when those timeouts entered dmesg. Before I made the tests with the .au file, I tried playing a mp3 using mpg123. Is there anything I can do to improve the audio on the sparc?
