Dear all, I have an Asus EEE PC 1215b with the following sound hardware ATI Technologies Inc Wrestler HDMI Audio [Radeon HD 6250/6310] 0403: 1002:1314 Subsystem: 1043:84a5 ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40) 0403: 1002:4383 (rev 40) Subsystem: 1043:841c With this hardware I have two different results depending on the distro that I run: * On ubuntu oneiric (11.10) live pendrive, the sound works out of the box and a PCM control exists in the mixer options. * On Debian Squeeze there is no PCM control and no sound comes out of the loudspeakers or headphone jack. Increasing the volume in "master" or "headphone" control does not have any effect. Since I want to use Debian over Ubuntu, I have tried to replicate the same version of programs of Ubuntu 11.10 in my Debian system. I have gone through the following steps: - Installing the same ubuntu kernel package that runs in the live-cd distribution. (3.0.0-12) - Backporting libasound2, alsa-base, alsa-utils and alsa-oss from the Ubuntu Oneiric source packages. (version 1.0.24) - Ensuring that no /etc/asound.conf or ~/.asoundrc files are present in the Debian system (as they are not present in the ubuntu live system). Having the same kernel (and therefore the same snd-* modules) and the same packages for alsa in userspace, I still don't understand why I don't get the PCM control out in my Debian system. I attach the alsa-info.sh results for both scenearios. Ubuntu (it works): http://pastebin.com/CXwVS2Dk Debian (it does not work): http://pastebin.com/NzXGH4D8 Note that the kernel modules are loaded with the same options, the differences are the following: * In Ubuntu there are pulseaudio and esd as sound servers (while there are none in Debian) * Ubuntu shows more accurate hardware info detection. It recognizes the PCI-ID of the sound card (probably the pci-id database is more up to date). * In the codec info parameters Ubuntu has a converter stream driver greater than 0: Node 0x02 [Audio Output] wcaps 0x1d: Stereo Amp-Out Control: name="Speaker Playback Volume", index=0, device=0 ControlAmp: chs=3, dir=Out, idx=0, ofs=0 Device: name="ALC269VB Analog", type="Audio", device=0 Amp-Out caps: ofs=0x57, nsteps=0x57, stepsize=0x02, mute=0 Amp-Out vals: [0x3d 0x3d] Converter: stream=5, channel=0 ^ | ------------------------- * A control PCM shows up in Ubuntu and not in Debian. control.12 { iface MIXER name 'PCM Playback Volume' value.0 255 value.1 255 comment { access 'read write user' type INTEGER count 2 range '0 - 255' tlv '0000000100000008ffffec1400000014' dbmin -5100 dbmax 0 dbvalue.0 0 dbvalue.1 0 } Any help or suggestion will be kindly appreciated.
