---------- Forwarded message ---------- From: Ludwig Maes <ludwig.maes(a)gmail.com> Date: 2009/6/26 Subject: Laptop speakers nonfunctional, jacks functional To: alsa-user(a)lists.sourceforge.net Realtek ALC888S (according to preinstalled Realtek HD audio manager on windows) visible jacks working, builtin laptop speakers and subwoofer silent. Running Ubuntu 9.04 compiled and installed alsa 1.0.20. http://www.alsa-project.org/db/?f=fb64ba9a8ab28d8c16532ece21e3adba7219e4b9 Notice it thinks it is ALC1200. I searched this and found it in patch_realtek.c, I changed the equality test so we would end up in ALC888 section... result was I got an extra volume control on mixer for BEEP. previously did not hear beeps when hitting down in terminal. BEEP is in headphones or line out. still not on speakers. aplay -l listed ALC888 too but codec#0 still showed ALC1200... I dont know the flow of information changes in ALSA to change this codec... I undid the equality test change and now its back to original realtek patch, recompiled reinstalled... added model=generic, to asound.state, this gave me more controls IIRC.. downloaded codecgraph utility, result: http://img20.imageshack.us/img20/8692/codec0.png I dont know how these codecgraphs work, but 4 jacks are right! the internal speakers appear twice?? how can one rewire these, or enable assuming dotted is disabled, does every amplifier triangle correspond to a volume control? is there a direct way to make changes? dmesg |grep hda: [ 16.172695] hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... [ 18.037866] ALSA /usr/src/alsa/alsa-driver-1.0.20/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:636: hda_intel: azx_get_response timeout, switching to polling mode: last cmd=0x00bb0000 Realtek datasheet for ALC888S, reference design, if helpful: http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PFid=28&a… I am very willing to test proposals... friendly greetings, Ludwig
