[alsa-devel] Altec Lansing FX5051 mixer
by Jeremy Nickurak 04 Apr '08

04 Apr '08

I recently purchased an Altec Lansing USB Surround speaker set. (It's a set of 5.1 speakers, with a built-in USB sound card). I've got about a week before the return policy expires and I'd have to return it. The mixer doesn't work at all w/linux kernel 2.6.22, everything is locked at 100% volume, which is pretty unhelpful, as it's the only way to adjust the volume. (no analog controls). Also, the digital control panel locks up when the speakers power up, further preventing any access to the volume controls. The device works out-of-the-box without any drivers under XP, so I have to so-far assume that alsa's usb-audio is missing something. Any thoughts as to what could be wrong? I'm more than happy to prod the device and submit any information I can extract about it, or even potentially opening the device up for remote access if a reputable developer is interested in examining it. -- Jeremy Nickurak -= Email/Jabber: atrus(a)rifetech.com =-

[alsa-devel] ALSA driver for Native Instruments sound hardware
by Daniel Mack 23 Mar '08

23 Mar '08

Hi, some months after the last posting, we finally managed to finish a new version of the ALSA driver for Native Instruments' external USB sound cards such as "Rig Kontrol 2", "Kore Kontroller", "Audio Kontrol 1" and "Audio 8 DJ". Compared to the last release, the following things were changed: - the streaming logic was completely reworked so that multiple substreams are handled correctly - a Linux input device layer was added to support the knobs, buttons and pedals on "Rig Kontrol 2" and "AudioKontrol 1" - workqueues were entirely removed from the code - most data structures are now allocated within one big struct to avoid multiple, smaller allocations - many more cleanups according to Clemens' reply on my last posting[1] The driver was properly tested with all the mentioned hardware on both record and playback channels. The patchset should apply to the current mecurial alsa-kernel tree. Please let me know what you think.

[alsa-devel] SALSA Lib - TLV Deprecated warnings
by J. Scott Merritt 22 Oct '07

22 Oct '07

It appears that if SALSA Lib 0.0.12 is built -without- TLV enabled in the configuration options, then simply -including- asoundlib.h from an application program will trigger deprecated warnings on some of the TLV read/write function definitions (even though they are not called from the application). Is there something we can do to the header files to eliminate these warnings ? Thanks, Scott.

[alsa-devel] Creative Labs XFi drivers.
by Tobin Davis 11 Oct '07

11 Oct '07

Creative Labs has released a proprietary driver base for their XFi cards. I downloaded it because it claims to have compatibility with alsa. In fact, it requires alsa include files to be able to compile. I haven't looked at the source yet (this information is all in the Readme.txt in the main download) and probably won't (especially since I don't own a Creative Labs XFi card). What I don't understand, is are they allowed to use our code to build their drivers? They use alsa core modules to interoperate (from what I can tell in the Readme.txt). Also, this line in the License.txt is especially troubling: > In the event that the Software includes Linux code or drivers, then, unless expressly stated to the contrary, such Linux > code and drivers are proprietary to Creative and all rights therein are reserved. I'm deleting all but the big tarball I downloaded. I'll delete it later. -- Tobin Davis <tdavis(a)dsl-only.net>

[alsa-devel] Alsa 1.0.15rc2 and oops with Dell M1210
by zhejiang 10 Oct '07

10 Oct '07

Seems that the spec->input_mux contains no item at all. So system maybe crash in the snd_hda_input_mux_info() when try to copy the items[].label,which is null pointer. May you replace the function stac92xx_mux_enum_info() in alsa-driver-1.0.15rc2/alsa-kernel/pci/hda/patch_sigmatel.c ? static int stac92xx_mux_enum_info(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_info *uinfo) { struct hda_codec *codec = snd_kcontrol_chip(kcontrol); struct sigmatel_spec *spec = codec->spec; printk("spec->input_mux->num_items is %d \n",spec->input_mux->num_items); if(!spec->input_mux->num_items) return 0; return snd_hda_input_mux_info(spec->input_mux, uinfo); } Does it still crash? What's the number of num_items? The pin_config for M1210 didn't include any input pin. I wonder why.

I tried 3 patches (incl. yours) and only yours helped partly at least. I patched Alsa 1.0.15rc3. Sound mutes as soon as I change volume, and I can only rmmod/modprobe snd-hda-intel to get it back. But Surround is working with your patch as I can see: "speaker-test -Dplug:surround51 -c6 -t waw" recognizes correctly all speakears. "speaker-test -c6 -t waw" does not recognize the speakers correctly, but it probably should not, or ?! MythTv is playing stereo files only on the right speakers. I do not now is this a MythTv or Alsa problem. probably MythTv and I should create a .asoundrc which should correct this somehow. I did not try hg, because I thought that Alsa 1.0.15rc3 is very new. Thanks. M.
