Add another finding here in case it is not mentioned before. ============ findings and investigation ==============
You can enable audio on ubuntu lucid as follows: 1. Add USER ubuntu to audio group /* this seems has been fixed in the latest Lucid */ # sudo usermod –aG audio ubuntu 2. Change pulse audio resample method sudo vi /etc/pulse/daemon.conf Change resample-method = speex-float-1 to resample-method = trivial 3. Sudo reboot Then you can choose audio output and get audio enabled. ==================== Conclusion ===================== Why we need to add ubuntu to audio group may be a bug of lucid (should have been fixed already). The resample method can be set to any other values except speex-float-N and it is caused by libspeex library issue. BTW, trival method cast least CPU and the quality is acceptable. ==================== speex fix ===================== The libspeex includes three resampling methods: fixed point, generic float point and SSE (intel specified float instruction set for X86). Debian/rules will detect ARCH and configure "correct" resampling method. Specially for X86, it will enable SSE. While for arm, it will enable fixed-point only by default and suppose your platform is armv4 which won’t support float-point. By comment out this armv4 rule (see below), we can enable float-point resample method on ARM, without effecting existing fixed-point. ifeq ($(DEB_HOST_ARCH_CPU),arm) objdir = $(objdir_fixedpoint) EXTRA_CONFIG_FLAGS = --enable-arm4-asm endif ==> ifeq ($(DEB_HOST_ARCH_CPU),arm) #objdir = $(objdir_fixedpoint) #EXTRA_CONFIG_FLAGS = --enable-arm4-asm endif -- Sound not working in all apps on dove https://bugs.launchpad.net/bugs/528524 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
