That is, % cat hoge.au > /dev/audio does not play back the tail part. % cat hoge.au hoge.au > /dev/audio plays back the first completely, but the last. The sound file is as follows: % file hoge.au ttt.au: Sun/NeXT audio data: 8-bit ISDN u-law, mono, 8012 Hz % ls -l ttt.au -rw-r--r-- 1 iwaki luser 6705 Aug 25 1997 hoge.au It looks like independent of brige drivers like sbc because the following two environments cause the same problem and others have reported the same probrem in Japanese mailing list.
