[alsa-devel] Virtual Surround, where to start
by Colin Nickerson 30 Aug '07

30 Aug '07

Hello everyone. I am a programmer but I do not have experience with ALSA. I would like to see if I can add software support for the SRS and other features of my M-Audio Revolution 7.1 card. How could I best start on this task? I am assuming that the card has some hardware acceleration for the SRS algorithms that I will need to access. thanks, colin

[alsa-devel] no sound with hda-intel, conexant venice chip on hp 2836
by Pieter-Augustijn Van Malleghem 30 Aug '07

30 Aug '07

hi, i've just installed debian unstable on an hp 2386ea. This is the sound card it uses: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) Subsystem: Hewlett-Packard Company Unknown device 30b2 The driver is snd-hda-intel and everything loads fine. Alsamixer does the job equally well. However, no actual sound is produced. It uses the Conexant Venice (cx20549) codec. Nothing special in dmesg. I tried loading the kernel with noacpi, but no changes. I attach alsa-info.txt. Any clues ?

[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

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
