There is Debian bug 354694 for this, http://bugs.debian.org/cgi- bin/bugreport.cgi?bug=354694
Problem is that pc-speaker event device is not on event0. It may change depending other event devices. So easy way to fix problem is to use beep command: beep -e /dev/input/by-path/platform-pcspkr-event-spkr <other parameters> I hope beep package maintainer will change default device from /dev/tty0 to this /dev/input/by-path/platform-pcspkr-event-spkr I don't know if alsamixer has anything to do with this. I have understood that alsamixer and pc-speaker is only when internal speaker is connected to audio-card input. Problem can be reproduced when /dev/input/by-path/platform-pcspkr-event-spkr is not pointing to /dev/input/event0 and then run command beep. Running: strace beep you'll find errors something like this: open("/dev/tty0", O_WRONLY) = 3 ioctl(3, 0x8000451a, 0x2ace0bbef0f8) = -1 EINVAL (Invalid argument) ** Also affects: beep (Debian) via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=354694 Importance: Unknown Status: Unknown -- The command 'beep' does not produce a sound https://bugs.launchpad.net/bugs/144022 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
