Hi all Since months we are trying to resolve sound problem on Acer Aspire 8920G laptops. It's High Definition Audio, 5.1 Cinematic Surround - Tuba. Other models with the same sound card have same problem.
Till now, we found only temporary solution witch enable two front speakers but today I found good news for us. Apparantly, Alsa developers together with Realtek has found solution in those latest driver (alsa- driver-1.0.19-5.11) on 2009/3/6. I found this on the Realtek official site. The only problem now is that I don't understand, very well, Ubuntu install and configuration instuctions from Realtek team. So if someone is able to get this 5.1 Surround work, please let us know with the step by step how-to like we do it on Ubuntu Forum. Thanks in advance. The new Alsa Realtek High Definition Audio Driver package is available here: http://www.realtek.com.tw/downloads/...?keyword=Linux The install and configuration instructions I don't understand well are: The source code copy from www.alsa-project.org. ver:3.3-4 Linux Source Code for ALC audio codec Support Codec list: ====AC97 Codec===== ALC100,100P ALC200,200P ALC650D ALC650E ALC650F ALC650 ALC655 ALC653 ALC658 ALC658D ALC850 ALC101 ALC202 ALC250 ALC203 ====HD Audio codec ==== ALC260 ALC262 ALC267 ALC268 ALC269 ALC272 ALC660 ALC660VD ALC662 ALC663 ALC861 ALC861VD ALC880 ALC882 ALC883 ALC885 ALC888 ALC889A Installation: This Source Code is from www.alsa-project.org. For OS installation, please remember add the Development tool kit. For driver installation, please follow below steps. Automatic install: (Recommend RedHat distribution) execute ./install Note: Ubuntu OS, please use manual install. Run commands need to add sudo at first words. Manual install: Step 1. unzip source code tar xfvj alsa-driver-1.0.xx.tar.bz2 Step 2. Turn on sound support from kernel config (soundcore module, default turn on) Step 3. Complied source code a. cd alsa-driver-1.0.xx b. ./configure c. make d. make install e. alsaconf f. ./snddevices (Only kernel 2.4 does it) Step 4. Edit your /etc/modules.conf or conf.modules depending on the distribution (Please refer to the attached modules.conf) snd-xxxx is the card ID. -- Azalia controller --ALC880 ALC882 ALC260 ALC262 ALC883 ALC885 ALC888 --- Intel ICH6 ICH7 --------- snd-hda-intel -- AC97 controller --ALC655 ALC650 ALC250 ALC255 --- Intel ICH6 ICH7 , SiS 7012 and NVidia---------- snd-intel8x0 --- Via8233 Via686a ------------------------------- snd-via82xx --- ATI Chipset ------------------------------- snd-atiixp Copy and paste this to the bottom of your /etc/modules.conf or /etc/modprobe.conf file. # ALSA portion alias char-major-116 snd alias snd-card-0 snd-xxxx # OSS/Free portion alias char-major-14 soundcore alias sound-slot-0 snd-card-0 # card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss Step 5. reboot your machine Step 6.

The most detail information, can refer the alsa-kernel/Documenttation/ALSA-Configuration.txt in the azx-021705.tar.bz2. 2. Kernel Version must be 2.2.14 or later. 3. All mixer channels are muted by default. You must use a native or OSS mixer program to unmute appropriate channels. 4. If can not compile the source code, try to rename the /usr/src/linux-2.x -> /usr/src/linux. 5. The driver added to support the SPDIF functoin. 6. a. You can download the alsa-lib-1.0.9 and alsa-utils-1.0.9a form the www.alsa-project.org, then unzip and install them. b. Suggest use "alsamixer" to control mixer function. c.
