I upgraded to Ubuntu 14.04 and now have no sound. This seems to be a common problem, but the answers on the Ubuntu forums aren't working for me.
#> aplay -l
aplay: device_list:268: no soundcards found...
I tried this
apt-get --purge remove linux-sound-base alsa-base alsa-utils
apt-get install linux-sound-base alsa-base alsa-utils
I tried this
modprobe snd-usb-audio
modprobe snd-hda-intel
I also reinstalled the kernel.
I tried following this, the speaker-test
produces "Playback device is default" output and seems to think it's working but there is no actual sound, then the guide directs me to procedure Ac which tells me to run this
echo "Sound cards recognized by the system:"; lspci -nn | grep --color=none '\[04[80][13]\]'; echo "Sound cards recognized by ALSA:"; lspci -nn | grep '\[04[80][13]\]' | while read line; do lspci -nnk | grep -A 3 '\[04[80][13]\]' | grep -e 'Kernel modules: ..*' -e '\[04[80][13]\]' | grep --color=none -F "$line"; done; echo "Sound cards recognized by ALSA, and activated:"; lspci -nn | grep '\[04[80][13]\]' | while read line; do lspci -nnk | grep -A 3 '\[04[80][13]\]' | grep -e 'Kernel drivers in use: ..*' -e '\[04[80][13]\]' | grep --color=none -F "$line"; done
which gives this output
Sound cards recognized by the system:
00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller [8086:1e20] (rev 04)
Sound cards recognized by ALSA:
00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller [8086:1e20] (rev 04)
Sound cards recognized by ALSA, and activated:
00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller [8086:1e20] (rev 04)
This seems to be in order but aplay -l
still says "no soundcards" and there is still no actual sound.
#> ls /dev/snd

There is no /etc/modprobe.d/blacklist-alsa.conf
Any other ideas?
