Have a fresh Arch Linux system setup.
After some Viber’s fixes (see the Viber: no connection – qt.network.ssl: Incompatible version of OpenSSL post) – sound system sometimes stops working.
It looks like next: run qmmp, press Play and:
[simterm]
... DecoderMAD: Fixed rate detected DecoderMAD: Total time: 297900 ReplayGain: disabled Dithering: disabled ALSA lib pcm_dmix.c:1108:(snd_pcm_dmix_open) unable to open slave OutputALSA: Error opening PCM device default OutputWriter: unable to initialize output StateHandler: Current state: FatalError; previous state: Stopped DecoderMAD: deleting input_buf OutputALSA: setupMixer() OutputALSA: setupMixer() success StateHandler: Current state: Stopped; previous state: FatalError ...

The solution
Check audio-devices and drivers:
[simterm]
$ lspci -knn|grep -iA2 audio
00:1b.0 Audio device [0403]: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller [8086:8c20] (rev 05)
Subsystem: ASUSTeK Computer Inc. 8 Series/C220 Series Chipset High Definition Audio Controller [1043:8576]
Kernel driver in use: snd_hda_intel
Kernel modules: snd_hda_intel
--
01:00.1 Audio device [0403]: NVIDIA Corporation GP107GL High Definition Audio Controller [10de:0fb9] (rev a1)
Subsystem: ASUSTeK Computer Inc. GP107GL High Definition Audio Controller [1043:8613]
Kernel driver in use: snd_hda_intel
Kernel modules: snd_hda_intel
[/simterm]
Create the /etc/modprobe.d/default.conf file:
options snd_hda_intel index=1
And reboot system.
Then check audio with for example speaker-test:
[simterm]
$ speaker-test -c2 speaker-test 1.1.8 Playback device is default Stream parameters are 48000Hz, S16_LE, 2 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 96 to 1048576 Period size range from 32 to 349526 Using max buffer size 1048576 Periods = 4 was set period_size = 262144 was set buffer_size = 1048576 0 - Front Left 1 - Front Right ^CTime per period = 10.940188
[/simterm]
Done.
