Classification: openSUSE Product: openSUSE 11.4 Version: Final Platform: 64bit OS/Version: openSUSE 11.4 Status: NEW Severity: Normal Priority: P5 - None Component: Sound AssignedTo: tiwai@novell.com ReportedBy: rameshmangal@hotmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Opera/9.80 (X11; Linux i686; U; en) Presto/2.8.131 Version/11.11 In openSUSE 11.4-32 bit default installation, I installed the suse version of skype, and it partially worked out of the box in terms of sound output and webcam input. The only issue remained was of Sound input. Never worked out, and I just left it alone. Few days later, removed PA completely, and alsa took over and worked well. Though that issue of sound input remained unsolved. Fast forwarded one-month, used tumbleweed. So presently, have kde 4.6.0 (from oss), kernel (from tumbleweed), alsa (from tumbleweed) and with all system updates (from the official update repo). Hardware: I have a HP-compaq laptop (CQ45-106 AU) with built-in microphone and speakers. These have always worked in windows vista in the other partition. I tried all the options in Skype to get the sound working. Same, if I let skype control the options, then it will be near-muted. While, if I dont let it, then there is the same noise.No matter which setting or input source I selected, there was always either a mute or a constant noise. 1. Research showed that you can use 'arecord' and 'aplay' from commandline to check the microphone. So I tried that, so as to differentiate whether the issue was in my setup or in the notorious Skype (very easy to blame). It came out the same kind of “static noise” was there from them as well. Conclusion: the problem is in system setup, rather than poor Skype. 2. The comprehensive alsa.conf by using this command. /usr/sbin/alsa-info.sh the particular link is: http://www.alsa-project.org/db/?f=998fe18d51a43271904e6fe694929d5ab9b019a0 There was some issue regarding muting of Capture 1 channel. So I used Kmix to unmute both capture channels. Just to be sure, also checked in alsamixer (cli). the /etc/modprobe.d/50-sound.conf options snd slots=snd-hda-intel,snd-hda-intel # 5Dex.oB+Yu+RuhF7:SBx00 Azalia (Intel HDA) alias snd-card-0 snd-hda-intel # l4dC.vfAxXUx5zd4:RS780 Azalia controller alias snd-card-1 snd-hda-intel Using trial and error to get sound working by force. the model options for trying to force alsa to try (one at a time) are these from the HD-Audio-Models.txt file in the alsa documentation in my case: STAC92HD71B* ============ ref Reference board dell-m4-1 Dell desktops dell-m4-2 Dell desktops dell-m4-3 Dell desktops hp-m4 HP mini 1000 hp-dv5 HP dv series hp-hdx HP HDX series hp-dv4-1222nr HP dv4-1222nr (with LED support) auto BIOS setup (default) I put a line at the top of the 50-sound.conf file (as root) like this options snd-hda-intel model=dell-m4-1 [then the rest of the file follows as it is] The first option of dell-m4-1 actually worked for me. Though, the number of channels have decreased, but sound output and sound input both are working. Also checked in skype and it works now. Hope this helps someone else too. Reproducible: Always Steps to Reproduce: 1. 2. 3. Expected Results: The auto setup should detect and work the sound input thing. without resorting to this particular thing. Software configuration: openSUSE 11.4 with tumbleweed repo. So, the kernel and alsa are from tumblweed repo. while kde and other alsa stuff are from official oss and update repos (completely patched). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
