[alsa-devel] SIIG-USB SoundWave 7.1 Pro
by John Dey 30 Aug '07

30 Aug '07

Hi, I have the above referenced sound card. It is running on the latest version of CCRMA x86. Jack shows only stereo. How do I configure so that I can run 5 channels. I haven't tried yet to look for directions on line. If someone could provide me with a URL to the most up-to-date instructions I would be willing to give it a try. Thanks. John

[alsa-devel] This is a nudge. This is only a nudge. In the event of actual emergency...
by Eric S. Raymond 30 Aug '07

There is a user community of significant size hanging on your next point release. Users of recent ThinkPads, especially X61 and T61s. ALSA 1.0.14 doesn't cut it for the AD1984 Intel sound card on these machines; your head revision, however, does. This is a nudge to your release manager. Please ship a point release soon so .deb and RPM packages con become available quickly. Owners of many laptops, including my X61, will thank you. -- <a href="http://www.catb.org/~esr/">Eric S.

[alsa-devel] [patch] ALC262 Input source bug on HP_BPC and HP_BPC_D7000
by zhejiang 30 Aug '07

30 Aug '07

Hi, I have a HP BPC D7000 machine and run fedora6 + alsa-1.0.14 on it. I found that when I used the front mic,I needed to choose the "Input source " as "Line" to record. Then I read the source code of alsa-1.0.14 and alsa-hg-20080828. I found that the capture_source items is wrong. I tried to fix and test them. It works well on my machine. When i read the source code, I found that the capture_source items of alc262_HP_capture_source[] are not suitable.In this patch,I fixed them, but i don't have the machine to test them. --- a/alsa-driver-hg20070828/alsa-kernel/pci/hda/patch_realtek.c 2007-08-24 08:00:06.000000000 +0800 +++ b/alsa-driver-hg20070828/alsa-kernel/pci/hda/patch_realtek.c 2007-08-29 12:47:30.000000000 +0800 @@ -7706,13 +7706,23 @@ .num_items = 5, .items = { { "Mic", 0x0 }, - { "Front Mic", 0x3 }, + { "Front Mic", 0x1 }, { "Line", 0x2 }, { "CD", 0x4 }, { "AUX IN", 0x6 }, }, }; +static struct hda_input_mux alc262_HP_D7000_capture_source = { + .num_items = 4, + .items = { + { "Mic", 0x0 }, + { "Front Mic", 0x2 }, + { "Line", 0x1 }, + { "CD", 0x4 }, + }, +}; + /* mute/unmute internal speaker according to the hp jack and mute state */ static void alc262_fujitsu_automute(struct hda_codec *codec, int force) { @@ -8313,7 +8323,7 @@ .hp_nid = 0x03, .num_channel_mode = ARRAY_SIZE(alc262_modes), .channel_mode = alc262_modes, - .input_mux = &alc262_HP_capture_source, + .input_mux = &alc262_HP_D7000_capture_source, }, [ALC262_HP_BPC_D7000_WL] = { .mixers = { alc262_HP_BPC_WildWest_mixer, @@ -8324,7 +8334,7 @@ .hp_nid = 0x03, .num_channel_mode = ARRAY_SIZE(alc262_modes), .channel_mode = alc262_modes, - .input_mux = &alc262_HP_capture_source, + .input_mux = &alc262_HP_D7000_capture_source, }, [ALC262_BENQ_ED8] = { .mixers = { alc262_base_mixer },

[alsa-devel] Time for ALSA 1.0.15-rc1?
by Takashi Iwai 29 Aug '07

29 Aug '07

Hi, How about considering about the 1.0.15-rc1 release? People tend to use still the old 1.0.14 release simply because it's THE last release. I'm too tired of answering "try HG version, the bug must have been fixed." We have already tons of changes, especially in the ALSA kernel/driver tree about 25,000 lines changes. That's high enough.

[alsa-devel] mic doesn't work with hda-intel/AD1983 driver
by Shuduo Sang 29 Aug '07

29 Aug '07

Hi, I am running ubuntu 7.04 on Dell Optiplex 745 with hda-intel card. The mic does not work now. I tried latest stable alsa driver. The chip is Analog Device AD1983. According to the document of alsa driver, there is no more model parameter can be set. Can anyone give me some information about that? Is it a defect of current driver code? Or something I missed? thanks, Regards, Sang Shuduo

[alsa-devel] Audiophile Delta 24/96 Midi Out continuously sends zeroes
by Romain Bossart 29 Aug '07

29 Aug '07

Hi, My audiophile 24/96 Midi Out sends zeroes continuously, so I can't use any instrument. I checked that with amidi by looking at the stream output of a connected instrument (midi out -> instrument -> midi in -> amidi). Zeroes are sent whether or not I try to send (normal) midi messages. I know it used some years ago (it was on win32 at that time). Midi In and the instrument do work perfectly. M-Audio answered me that they don't yet support linux. I'm using alsa 1.0.14 on debian/sid 2.6.22. Anyone has an idea? Thank you Romain

[alsa-devel] [patch] kernel-sync
by Trent Piepho 28 Aug '07

28 Aug '07

Here's patch for alsa-kernel to sync bt87x.c with the git kernel, from commit cf784d554fdb94f21671830135dba56b507126cf Or maybe process is to wait for 2.6.23 to be released, and then sync to that? I have some more patch to bt87x, but I'm waiting for this to appear in alsa-kernel so I can base them off it.

[alsa-devel] echo-cancellation plugin advice?
by Robert Brewer 28 Aug '07

28 Aug '07

I'm writing a small speech input app for my laptop. My app is unusable when other sounds are being generated by the laptop, such as from a music playing app. For this reason, I'd like to have an echo cancellation plugin that would cancel out the music played on the laptop speakers when it is received by the mic. I think this should be doable since the music is playing through alsa. I've done some poking in the plugin documentation, and it's not clear to me how to architect this plugin. Ideally, I would route all my music playing apps through the echo cancelling plugin. I would also route the mic capture stream through the plugin. So the plugin must handle both playback and capture streams. Does the asym plugin hold the answers I need? Does anyone have any thoughts on how I might do this? There are several open source echo cancellation algorithms available, so I'm mainly asking for advice on implementing this as an alsa plugin. Thanks, Rob -- Robert W. Brewer
