[arch-general] Broken sound with Linux 3.9.2 on Acer laptop
After upgrading to 3.9.2 kernel, the sound did not work. However, the system CAN recognize my sound card, and my sound card appeared in `alsamixer` Downgrading the kernel can solve the problem. Providing more info: Acer Aspire laptop, with Intel i5 CPU, 2nd generation SandyBridge. `uname -a`:

“Did not work” mean no sound at all? Or can you hear crap or something?

I wonder about “float32le”. I think the default is s16le. Try to change this in /etc/pulse/daemon.conf—maybe the conversion is too much. Regards, Olli
Hello BlissSam,
After upgrading to 3.9.2 kernel, the sound did not work. However, the system CAN recognize my sound card, and my sound card appeared in `alsamixer` Downgrading the kernel can solve the problem.
Providing more info:
Acer Aspire laptop, with Intel i5 CPU, 2nd generation SandyBridge.
`uname -a`:
Linux brilliant-laptop 3.9.2-1-ARCH #1 SMP PREEMPT Sat May 11 20:31:08 CEST 2013 x86_64 GNU/Linux

lspci -nn | grep Audio could provide some info susceptible to help. snd_hda_intel apply treat differently hda intel hardware differently depending on device id. Explore a little bit files content under /proc/asound Such as: /proc/asound/cards /proc/asound/devices /proc/asound/pcm /proc/asound/card0/codec* Fallback to simple stuff such as speaker-test -c2 aplay somewavfile.wav aplay -l aplay -L I have found it useful and very interesting to do strace -e trace=open speaker-test -c2 That shows you all config files that alsa-lib opens. ________________________________ CONFIDENTIALITY : This e-mail and any attachments are confidential and may be privileged.

The problem will be fixed in 3.9.3 kernel and thanks for all your help! Link: https://bugzilla.kernel.org/show_bug.cgi?id=58351
