| Hi all, I'm trying to install the sound drivers on a Fujitsu-Siemens Stylistic ST5112 tablet PC. The machine has an Intel chipset recognized by the usual hda-intel driver (8086:27d8, subsystem ID 10cf:13b4), but I cannot make it work properly. With the ALSA drivers v. 1.0.17, the codec is recognized as a SigmaTel STAC9228 (vendor ID 0x83847616) and I do get proper mixer/playback/capture devices. The problem is that the playback output, while being audible immediately after loading the driver, fades away in around 20-30 seconds, to the point where nothing is heard any more. Nothing happens automatically in alsamixer, and it seems that no amount of fiddling can take it back. Only removing and reloading the card driver makes the sound come momentarily back; then it fades away again. I have tried all the "model=" settings for STAC9228, without any success. I've found a similar problem at http://forums.opensuse.org/hardware/389637-sound-slowly-fades-out-when-connecting-phones-speakers.html, but unfortunately "model=3stack" did not solve the issue for me. Dmesg reports: [ 588.986927] PCI: Found IRQ 11 for device 0000:00:1b.0 [ 588.986927] PCI: Setting latency timer of device 0000:00:1b.0 to 64 [ 589.023495] ALSA /root/alsa-driver-1.0.17.dfsg/pci/hda/hda_codec.c:3030: autoconfig: line_outs=2 (0xa/0xd/0x0/0x0/0x0) [ 589.023495] ALSA /root/alsa-driver-1.0.17.dfsg/pci/hda/hda_codec.c:3034: speaker_outs=1 (0xb/0x0/0x0/0x0/0x0) [ 589.023495] ALSA /root/alsa-driver-1.0.17.dfsg/pci/hda/hda_codec.c:3038: hp_outs=0 (0xd/0xd/0x0/0x0/0x0) [ 589.023495] ALSA /root/alsa-driver-1.0.17.dfsg/pci/hda/hda_codec.c:3039: mono: mono_out=0x0 [ 589.023495] ALSA /root/alsa-driver-1.0.17.dfsg/pci/hda/hda_codec.c:3047: inputs: mic=0xc, fmic=0xe, line=0x0, fline=0x0, cd=0x0, aux=0x0 [ 589.023495] ALSA /root/alsa-driver-1.0.17.dfsg/pci/hda/../../alsa-kernel/pci/hda/patch_sigmatel.c:2371: dac_nids=1 (0x2/0x0/0x0/0x0/0x0) The complete alsa-info.txt output is at http://pastebin.ca/1205193 . With the latest snapshot of 1.0.18rc3 the codec is no longer even recognized; alsa-info.sh output is at http://pastebin.ca/1205197 . I'll be definitely grateful for any hints on how to get this working! Thanks a lot in advance, -- Emanuele |
