[alsa-devel] Buffer Overrun Messages
by John Dey 24 Apr '07

24 Apr '07

Hi, I have been driving fluidsynth with with aplaymidi and get the following: fluidsynth: ALSAsequencer buffer overrun, lost event. I have played around with buffer size and buffer number and also run with and without jackd. The sound out doesn't seem to be affect. Can anyone give me some guidance on how to eliminate the error. Could the error be caused by fluidsynth? I have also run the program on PS2/Yellowdog linux and CCRMA fc5 (x86) both with similar results. Thanks. John

Re: [alsa-devel] Fwd: No sound with ATI SB450
by Ben DiDonc 23 Apr '07

Tobin, Unfortunately, ACPI was on at all times. My laptop hardly ever boots without ACPI (randomly, the SATA driver fails before it can even mount the root partition). I ran some more tests today: I loaded Ubuntu Edgy from the live CD where the sound chip used to work (kernel 2.6.17, alsa driver 1.0.12rc1). Obviously the sound works straight away. From there , I ran the same series of test: download and build (--with-debug=detect) the next version of alsa-driver, run a capture from mic and try playing it back, check syslog and run alsa-info.sh. I did this for successive versions of alsa-driver (starting with 1.0.12) until it fails. Here are the results: Alsa driver 1.0.12rc1(shipped with edgy): capture: working, playback working, alsa-info.sh at http://pastebin.ca/453947 Alsa driver 1.0.12: (alsa-info.sh at http://pastebin.ca/453971 ) syslog lines after modprobe: ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 233 ALSA alsa-driver-1.0.12/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:663: codec_mask = 0x9 hda_codec: Unknown model for ALC861, trying auto-probe from BIOS...

ALSA hda_intel.c:696: codec_mask = 0x9 capture and playback dont work. Summary: I tried alsa-driver 1.012 through to 1.0.14rc3 on ubuntu edgy (kernel 2.6.17). 12 and 13 work fine, 14rc1 and 2 capture works but not playback, 14rc3 doesnt detect the codec.

[alsa-devel] Strange code in
by Pete Zaitcev 23 Apr '07

23 Apr '07

Dear Takashi: Hans de Goede (on cc:) hits a problem when snd-usb-audio breaks with: "USB device is in the shutdown state, cannot create a card instance". This is how the place looks: chip = NULL; for (i = 0; i < SNDRV_CARDS; i++) { if (usb_chip[i] && usb_chip[i]->dev == dev) { if (usb_chip[i]->shutdown) { snd_printk(KERN_ERR "USB device is in the shutdown state, cannot create a card instance\n"); goto __error; } chip = usb_chip[i]; break; } } The code looks broken to me, because dev at this time is a new device structure, freshly allocated. You cannot compare it with an old instance, and I don't know why you would want to. Unfortunately (for fortunately), I have zero clue about the way ALSA works, specifically rules for snd_device_ops.dev_free, so I am asking you to look at this problem. Yours, -- Pete

[alsa-devel] [PATCH] sound: fix incorrect use of platform_device_register()
by Akinobu Mita 23 Apr '07

23 Apr '07

The platform_device allocated by platform_device_alloc() should be added to the device hierarchy by platform_device_add() instead of platform_device_register(). Otherwise it will hit WARN_ON() in platform_device_register(). by illegal refcount. This patch fixes such incorrect usages in portman2x4 and mts64 drivers. Also it removes unnecessary trailing whitespaces.

Re: [alsa-devel] Problem with Conexant
by Tobin Davis 23 Apr '07

Did you try adjusting the PCM volume levels? They may be set too low. That particular sound chip required a lot of manipulating to get functional, and is still very problematic. Unfortunately, I have no way of testing it, so users (like yourself) have to be my ears. The last time I worked with that particular configuration, the user that was testing said that it took a bit of tweaking with the PCM and other volume levels to get good sound.

[alsa-devel] Problem with Conexant
by Black X 23 Apr '07

23 Apr '07

Ok, I try that before and try it now, still no change, and still have the same problem. When I highest the sound volume of headphone this makes sound starting noisy (and that's the same with PCM). About speaker it's work fine, but IF I moving any window or rotate the desktop cube this makes the sound very slow with noise.

[alsa-devel] partial fix for bug #2708: [ALSA - driver] PCI - hda-intel
by Jeffrey Arbuckle 23 Apr '07

23 Apr '07

Using alsa-driver-1.0.14rc3 with an iMac Core2 Duo 24" results in audio only available through the headphones. Additionally the sound is very low, even at the highest mixer setting. This problem is very similar to the bug recently fixed in 1.0.14rc2 with the audio on the MacPro. I was able to make a patch that applies the same fix for the MacPro to my iMac. The patch fixes the audio so that the built in speakers work normally, but now the headphones do not work at all. Obviously some more work is needed on this. The patch I've attached just adds my device's' PCI SSID to an existing switch statement. I am willing to provide some more testing if necessary. Here is my systems info: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) Subsystem: Realtek Semiconductor Co., Ltd.
