Ok, I did the tests you have proposed and I'm having the same issue here. mplayer works for 48khz ac3 file you've provided but only for -ao alsa:device=iec958, giving device=hw=0.1 gives noise.
What is interesting - doing tests which cause a noise (with hw=0.1) , will make device=iec958 method fail too. Only alsa force-reload will bring back proper behavior. 44khz files gives noise. VLC set up to use ALSA hw0,1 fails for both files, I'm having noise. same with aplay -D hw:0,1 to...@hardc0re:~$ cat /etc/issue Ubuntu 10.10 \n \l to...@hardc0re:~$ aplay -l **** Lista PLAYBACK urządzeń **** karta 0: Intel [HDA Intel], urządzenie 0: AD198x Analog [AD198x Analog] Urządzenia podrzędne: 1/1 Urządzenie podrzędne #0: subdevice #0 karta 0: Intel [HDA Intel], urządzenie 1: AD198x Digital [AD198x Digital] Urządzenia podrzędne: 1/1 Urządzenie podrzędne #0: subdevice #0 to...@hardc0re:~$ uname -a Linux hardc0re 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:36:48 UTC 2010 i686 GNU/Linux to...@hardc0re:~$ dpkg -l alsa-base Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Nazwa Wersja Opis +++-==============-==============-============================================ ii alsa-base 1.0.23+dfsg-1u ALSA driver configuration files to...@hardc0re:~$ -- ALSA SPDIF IEC958 output no longer bit perfect (regression) https://bugs.launchpad.net/bugs/358118 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
