I didn't see anything though. But that just means nothing obvious is wrong! ;) Could still be a bunk component in there somewhere. For the record, only the worst cases of dry solder joint are visible. When suspecting bad joints, your best chance is to resolder almost everything until you're bored or you card works again. Whichever happens first. When heating a joint, if you hear hissing or poping sounds, it means that the joint was probably in bad shape. I usually start by the biggest joints, work 1/2 hour, re-test, resolder 1/2 hour, re-test... No matter---I got the replacemnt request approved from the retailer, so hopefully I'll have a new one in a couple weeks or so. Good news.

[Alsa-user] Multiple things sending to Alsa
Hi, Apologies for the apalling subject line. I have a Toshiba satellite pro [never buy one] which runs Ubuntu Gutsy with an Intel HDA built in soundcard. I have compilted alsa 1.16 with the apropriate options (according to the hda-intel ubuntu howto: https://help.ubuntu.com/community/HdaIntelSoundHowto ), and I get sound out. What I don't have is that on my PC, I can play sounds with clients connected to Jack to Alsa which makes sound, at the same time as playing music through some player connected directly to alsa (not using jack). Unable to do this on my laptop. The problem is that I have no idea where to start looking for the problem. Other problems include not being able to kill processes using the soundcard (revealed with lsof /dev/snd/*) that belong to programs that have crashed, so the soundcard remains blocked (kill -9 pid doesn't seem to work). If anyone knows of an apropriate fm that I can rt then that would be great or any options that I should have included at compile time. Or even better if anyone can explain what's going on I'd really appreciate the time. Apologies if this is stupid; I have tried googling lots as I'm sick of these two problems.

Re: [Alsa-user] Input feedback on snd-hda-intel with SigmaTel STAC9221 A1
Hi, I also have this setup - on a Dell M2010 running Ubuntu 8.04 I'm unable to get any sound from the on-board speakers - only the headphone jack works. My alsa-info is at: http://pastebin.ca/1000180 There's also a codecgraph output svg at http://www.box.net/shared/5jpeiw800o Any advice would be very gratefully received.

The default is, but if you install the alsa-plugins package (and libsamplerate) and add a line defaults.pcm.rate_converter samplerate Or speexrate. This is usually much faster. And forgot to write: you don't have to add anything to asoundrc for speexrate plugin. Install it, then alsa-lib will pick it up automatically. Takashi After some web search I see that there are several quality settings for speexrate. How does one choose/change the quality settings ? Use speexrate_best instead of speexrate, for example. See alsa-plugins/doc/speexrate.txt for details. Takashi Thanks. I've just read /usr/share/doc/packages/alsa-plugins/speexrate.txt file and I understand its contents, specifically, the Or, more easily, define a global variable defaults.pcm.rate_converter, which is used as the default converter type by plug and rate plugins: defaults.pcm.rate_converter speexrate Write the above in your ~/.asoundrc or /etc/asound.conf. part this way: I can edit /etc/asound.conf file and add, say, defaults.pcm.rate_converter speexrate_best line anywhere in the /etc/asound.conf file, Is this understanding correct ? Yes. I read the file on my SUSE 10.3. laptop, hope it's good enough version. ... I've just discovered there is no /etc/asound.conf file on my laptop: [EMAIL PROTECTED]:~ ls /etc/asound* /etc/asound.state [EMAIL PROTECTED]:~ . Should I create /etc/asound.conf ? Should it contain just one defaults.pcm.rate_converter speexrate_best line ? Yes. But I guess you barely notice the difference of output quality from the default speexrate (although you'll notice the difference of CPU usage :) Takashi - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
