I have Kubuntu 14.04 64-bit on an AMD box. I have Coax Digital IEC958 sound output to an audio receiver. After startup, sound works for a while (10-15 min), and thereafter (kmix) volume falls to zero - no sound thereafter. I can adjust sound in kmix, but it will invariably do the same thing.
I cannot find any relevant messages in dmesg or syslog.
I have Asus K55V, fedora 17 64 biti instaled. I have audio from laptop, but I canot use an audio sistem because when I connect the audio jack in audio out port, it doesn't get out any sound anymore. The sound from laptop stops and audio sistem doesn't work either. In win 7 it works OK. The sound hard from my laptop is provided by realteck.
I use Dell XPS L502x laptop to watch movies. F19 worked perfectly, but with F20 I have audio issue. If laptop is connected through MiniDisplayPort to external TV then I have to tweak audio settings in smplayer and vlc to get any sound. In XBMC I can't get any sound at all. If laptop is not connected to TV, then no problems.
i am having an sony E series laptop.i have an HDMI port .at this stage ,i have tested my sound card , which provides audio out on my laptop i.e i could hear songs .my laptop has two sound cards amd 5450 and an intel-hda(alsamixer shows that as s/pdif) .
I recently installed ubuntu 13.10 and am having trouble with no sound output. This was never an issue with 11, which was the last one I used. I am using an HDMI cable for video and audio this time rather than the vga and I'm not sure if that is an issue or not.
Recently I have upgraded my Asus B43s from 12.04 to 12.04 HWE and have lost all audio upon start up. When going to the sound setting, there are no devices available. Once I run command "lspci | grep Audio" in the terminal, my audio comes back. If I shutdown or restart, I have to do the same thing over again before the sound is available.
