 Posted: Sat Aug 06, 2011 4:39 am Post subject: [SOLVED] No sound from ALSA after upgrading kernel to 3.0 |
 |
|
As the title states. I'm using vanilla-sources 3.0 and 3.0.1 now with the same results. Audio worked fine up until 2.39.3 and works on a similar machine.
My initial attempt at installing 3.0 was done by doing a make oldconfig. When that didn't work, I performed a make mrproper and went through each setting in menuconfig. When THAT failed, I removed the sources and started completely from scratch.
I'm using an ATi Radeon HD 3200 IGP with audio over HDMI.
| Code: |
lspci -n
00:14.2 0403: 1002:4383
01:05.0 0300: 1002:9610
|
Here is my .config
| Code: |
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC889A Analog [ALC889A Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: ALC889A Digital [ALC889A Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
|
As mentioned, I have a similiar machine except with an HD 3300 IGP that works fine over HDMI. I've glanced at each config and haven't seen any differences between the two.
This evening, I tried 3.0.1 without any love. I've removed /etc/asound.conf and ~/.asoundrc, toggled each trigger in alsamixer, no luck. Since this works perfectly fine with <=2.6.39, I'm assuming this has to be a kernel bug or some configuration that I've overlooked.
Help?

| Try using alsamixer -c0 or alsamixer -c1 to unmute the main/front outputs. From the aplay -l output, it seems the kernel has recognized and loaded the proper drivers, as udev has created the device nodes for aplay to list them. |

Already did that. I've also tried using speaker-test and specifying each output without any luck.

| I would try compiling the latest alsa-driver snapshot, which will overwrite the kernel modules (snd.ko, etc. under /lib/modules/). |

Found the answer. This commit requires a modification to my boot options.
I tacked on radeon.audio=1 and I suddenly have audio. I don't have a display port, so I'm not sure why this machine was affected, but it works.

I was just affected by this problem. And don't like this solution. Hope it's temporary.
edit: I think you should add HDMI or radeon to the topic title, to make it easier for people with the same problem to reach the solution. |
