Are you using pulseaudio? If yes try to stop pulseaudio and start it again, worked for me pulseaudio -k pulseaudio -D
If Thunderbird tries to fetch a mail, before I did this, it also freezes as it uses sound alert when a mail is received. Either disable this or try to restart pulseaudio after suspend -- Thunderbird stalls while sound is suspended https://bugs.launchpad.net/bugs/203352 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
