ALC1220 DualCodec - changing to headphone (front panel) port doesn't work without toggling pro audio profile
by GitHub issues - edited 29 Mar '23

29 Mar '23

alsa-project/alsa-ucm-conf issue #299 was edited from metronidazole: I have a Gigabyte x570 aorus pro motherboard with the ALC1220 audio device using the dualcodec model. I have two issues: A. jack sense doesnt work. I'm not sure if this is a UCM thing, but in my desktop environment (KDE Plasma 5.27) the headphones port shows as "unplugged" in system settings, and hdajacksensetest shows it as not detected "Pin 0x1b (Green Headphone, Front side): present = No". this is a minor issue B. more importantly, when i want to use my frontpanel headphones input, i have to do the following work around otherwise no sound comes out: 1. Start with Profile set to 'analog stereo output' and port 'line out' 2. Plug in headphones and set port to 'headphones (unplugged)' -> sound stops from speakers (rear line out port) and there is no output from the headphoens 3. Set profile to pro audio -> audio comes through headphones (front port). **to return back to speakers (rear out)** 4. Set profile to analog stereo output) and change the port to 'headphones (unplugged)' and then back to 'line out' -> sound comes out of speakers I have attached some debug info below: [alsa-info.txt](https://github.com/alsa-project/alsa-ucm-conf/files/11099085… [alsaucm.txt](https://github.com/alsa-project/alsa-ucm-conf/files/11099087/a… Any help would be appreciated Issue URL : https://github.com/alsa-project/alsa-ucm-conf/issues/299 Repository URL: https://github.com/alsa-project/alsa-ucm-conf

[PATCH 0/4] ALSA: ymfpci: PM related cleanups and fixes
by Tasos Sahanidis 29 Mar '23

29 Mar '23

Hi, This series started while attempting to fix the OPL not being detected after restoring from S4 on a YMF744. While attempting to debug the issue, it was found that SIMPLE_DEV_PM_OPS was deprecated, and thus replaced, and a few cleanups were made along the way.

[PATCH] ALSA: ymfpci: Add error messages for abritrary IO ports on older chips
by Tasos Sahanidis 29 Mar '23

29 Mar '23

As an end user, it can be confusing to request an arbitrary IO port be used only to find out that it doesn't work without an obvious reason, especially since /sys/module/snd_ymfpci/parameters/{fm,joystick,mpu}_port indicate 0 after the module has been loaded. In my case, I was unaware that the YMF724 did not support such usage, and thus ended up spending time attempting to debug the issue. Now, when a user attempts to request an IO port that isn't supported by the hardware, the following message is printed: [ 25.549530] snd_ymfpci 0000:06:05.0: The Yamaha DS-1 (YMF724F) does not support arbitrary IO ports for FM (requested 0x1234) Signed-off-by: Tasos Sahanidis <tasos(a)tasossah.com> --- sound/pci/ymfpci/ymfpci.c | 35 +++++++++++++++++++++++++---------- 1 file changed, 25 insertions(+), 10 deletions(-) diff --git a/sound/pci/ymfpci/ymfpci.c b/sound/pci/ymfpci/ymfpci.c index 1e198e4d5..de5dc5337 100644 --- a/sound/pci/ymfpci/ymfpci.c +++ b/sound/pci/ymfpci/ymfpci.c @@ -98,8 +98,10 @@ static int snd_ymfpci_create_gameport(struct snd_ymfpci *chip, int dev, case 0x204: legacy_ctrl2 |= 2 << 6; break; case 0x205: legacy_ctrl2 |= 3 << 6; break; default: - dev_err(chip->card->dev, - "invalid joystick port %#x", io_port); + if (io_port > 0) + dev_err(chip->card->dev, + "The %s does not support arbitrary IO ports for the game port (requested 0x%x)\n", + chip->card->shortname, (unsigned int)io_port); return -EINVAL; } } @@ -186,6 +188,13 @@ static int snd_card_ymfpci_probe(struct pci_dev *pci, default: model = str = "???"; break; } + strcpy(card->driver, str); + sprintf(card->shortname, "Yamaha %s (%s)", model, str); + sprintf(card->longname, "%s at 0x%lx, irq %i", + card->shortname, + chip->reg_area_phys, + chip->irq); + legacy_ctrl = 0; legacy_ctrl2 = 0x0800; /* SBEN = 0, SMOD = 01, LAD = 0 */ @@ -218,7 +227,13 @@ static int snd_card_ymfpci_probe(struct pci_dev *pci, case 0x398: legacy_ctrl2 |= 1; break; case 0x3a0: legacy_ctrl2 |= 2; break; case 0x3a8: legacy_ctrl2 |= 3; break; - default: fm_port[dev] = 0; break; + default: + if (fm_port[dev] > 0) + dev_err(card->dev, + "The %s does not support arbitrary IO ports for FM (requested 0x%x)\n", + card->shortname, (unsigned int)fm_port[dev]); + fm_port[dev] = 0; + break; } if (fm_port[dev] > 0) fm_res = devm_request_region(&pci->dev, fm_port[dev], @@ -234,7 +249,13 @@ static int snd_card_ymfpci_probe(struct pci_dev *pci, case 0x300: legacy_ctrl2 |= 1 << 4; break; case 0x332: legacy_ctrl2 |= 2 << 4; break; case 0x334: legacy_ctrl2 |= 3 << 4; break; - default: mpu_port[dev] = 0; break; + default: + if (mpu_port[dev] > 0) + dev_err(card->dev, + "The %s does not support arbitrary IO ports for MPU-401 (requested 0x%x)\n", + card->shortname, (unsigned int)mpu_port[dev]); + mpu_port[dev] = 0; + break; } if (mpu_port[dev] > 0) mpu_res = devm_request_region(&pci->dev, mpu_port[dev], @@ -257,12 +278,6 @@ static int snd_card_ymfpci_probe(struct pci_dev *pci, if (err < 0) return err; - strcpy(card->driver, str); - sprintf(card->shortname, "Yamaha %s (%s)", model, str); - sprintf(card->longname, "%s at 0x%lx, irq %i", - card->shortname, - chip->reg_area_phys, - chip->irq); err = snd_ymfpci_pcm(chip, 0); if (err < 0) return err; -- 2.25.1

[PATCH] ALSA: ymfpci: Create card with device-managed snd_devm_card_new()
by Tasos Sahanidis 29 Mar '23

snd_card_ymfpci_remove() was removed in commit c6e6bb5eab74 ("ALSA: ymfpci: Allocate resources with device-managed APIs"), but the call to snd_card_new() was not replaced with snd_devm_card_new(). Since there was no longer a call to snd_card_free, unloading the module would eventually result in Oops: [697561.532887] BUG: unable to handle page fault for address: ffffffffc0924480 [697561.532893] #PF: supervisor read access in kernel mode [697561.532896] #PF: error_code(0x0000) - not-present page [697561.532899] PGD ae1e15067 P4D ae1e15067 PUD ae1e17067 PMD 11a8f5067 PTE 0 [697561.532905] Oops: 0000 [#1] PREEMPT SMP NOPTI [697561.532909] CPU: 21 PID: 5080 Comm: wireplumber Tainted: G W OE 6.2.7 #1 [697561.532914] Hardware name: System manufacturer System Product Name/TUF GAMING X570-PLUS, BIOS 4408 10/28/2022 [697561.532916] RIP: 0010:try_module_get.part.0+0x1a/0xe0 [697561.532924] Code: 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 0f 1f 44 00 00 55 48 89 e5 41 55 41 54 49 89 fc bf 01 00 00 00 e8 56 3c f8 ff <41> 83 3c 24 02 0f 84 96 00 00 00 41 8b 84 24 30 03 00 00 85 c0 0f [697561.532927] RSP: 0018:ffffbe9b858c3bd8 EFLAGS: 00010246 [697561.532930] RAX: ffff9815d14f1900 RBX: ffff9815c14e6000 RCX: 0000000000000000 [697561.532933] RDX: 0000000000000000 RSI: ffffffffc055092c RDI: ffffffffb3778c1a [697561.532935] RBP: ffffbe9b858c3be8 R08: 0000000000000040 R09: ffff981a1a741380 [697561.532937] R10: ffffbe9b858c3c80 R11: 00000009d56533a6 R12: ffffffffc0924480 [697561.532939] R13: ffff9823439d8500 R14: 0000000000000025 R15: ffff9815cd109f80 [697561.532942] FS: 00007f13084f1f80(0000) GS:ffff9824aef40000(0000) knlGS:0000000000000000 [697561.532945] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [697561.532947] CR2: ffffffffc0924480 CR3: 0000000145344000 CR4: 0000000000350ee0 [697561.532949] Call Trace: [697561.532951] <TASK> [697561.532955] try_module_get+0x13/0x30 [697561.532960] snd_ctl_open+0x61/0x1c0 [snd] [697561.532976] snd_open+0xb4/0x1e0 [snd] [697561.532989] chrdev_open+0xc7/0x240 [697561.532995] ? fsnotify_perm.part.0+0x6e/0x160 [697561.533000] ? __pfx_chrdev_open+0x10/0x10 [697561.533005] do_dentry_open+0x169/0x440 [697561.533009] vfs_open+0x2d/0x40 [697561.533012] path_openat+0xa9d/0x10d0 [697561.533017] ? debug_smp_processor_id+0x17/0x20 [697561.533022] ? trigger_load_balance+0x65/0x370 [697561.533026] do_filp_open+0xb2/0x160 [697561.533032] ? _raw_spin_unlock+0x19/0x40 [697561.533036] ? alloc_fd+0xa9/0x190 [697561.533040] do_sys_openat2+0x9f/0x160 [697561.533044] __x64_sys_openat+0x55/0x90 [697561.533048] do_syscall_64+0x3b/0x90 [697561.533052] entry_SYSCALL_64_after_hwframe+0x72/0xdc [697561.533056] RIP: 0033:0x7f1308a40db4 [697561.533059] Code: 24 20 eb 8f 66 90 44 89 54 24 0c e8 46 68 f8 ff 44 8b 54 24 0c 44 89 e2 48 89 ee 41 89 c0 bf 9c ff ff ff b8 01 01 00 00 0f 05 <48> 3d 00 f0 ff ff 77 32 44 89 c7 89 44 24 0c e8 78 68 f8 ff 8b 44 [697561.533062] RSP: 002b:00007ffcce664450 EFLAGS: 00000293 ORIG_RAX: 0000000000000101 [697561.533066] RAX: ffffffffffffffda RBX: 0000000000000003 RCX: 00007f1308a40db4 [697561.533068] RDX: 0000000000080000 RSI: 00007ffcce664690 RDI: 00000000ffffff9c [697561.533070] RBP: 00007ffcce664690 R08: 0000000000000000 R09: 0000000000000012 [697561.533072] R10: 0000000000000000 R11: 0000000000000293 R12: 0000000000080000 [697561.533074] R13: 00007f13054b069b R14: 0000565209f83200 R15: 0000000000000000 [697561.533078] </TASK> Fixes: c6e6bb5eab74 ("ALSA: ymfpci: Allocate resources with device-managed APIs") Signed-off-by: Tasos Sahanidis <tasos(a)tasossah.com> --- sound/pci/ymfpci/ymfpci.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sound/pci/ymfpci/ymfpci.c b/sound/pci/ymfpci/ymfpci.c index 1e198e4d5..82d4e0fda 100644 --- a/sound/pci/ymfpci/ymfpci.c +++ b/sound/pci/ymfpci/ymfpci.c @@ -170,7 +170,7 @@ static int snd_card_ymfpci_probe(struct pci_dev *pci, return -ENOENT; } - err = snd_card_new(&pci->dev, index[dev], id[dev], THIS_MODULE, + err = snd_devm_card_new(&pci->dev, index[dev], id[dev], THIS_MODULE, sizeof(*chip), &card); if (err < 0) return err; -- 2.25.1

[PATCH v2 0/4] ASoC: remove unnecessary dai_link->platform
by Kuninori Morimoto 29 Mar '23

29 Mar '23

Hi Mark Current ASoC will ignore already connected component when binding Card. This will happen mainly "CPU Component" is handled as "Platform Component", which was needed before. static int snd_soc_rtd_add_component(...) { ... for_each_rtd_components(rtd, i, comp) { /* already connected */ if (comp == component) return 0; } ... } Some drivers are still using CPU or Dummy Component as Platform Component, but these are no meaning or ignored. This patch-set remove these. v1 -> v2 - remove the patch for simple-card - remove extra simple-card patch - add Acked-by for atmel patch Link: https://lore.kernel.org/r/878rfyjz4p.wl-kuninori.morimoto.gx@renesas.com Kuninori Morimoto (4): ASoC: fsl: remove unnecessary dai_link->platform ASoC: atmel: remove unnecessary dai_link->platform ASoC: ti: remove unnecessary dai_link->platform ASoC: soc-topology.c: remove unnecessary dai_link->platform sound/soc/atmel/atmel-classd.c | 5 +---- sound/soc/atmel/atmel-pdmic.c | 5 +---- sound/soc/fsl/imx-audmix.c | 14 ++++---------- sound/soc/fsl/imx-spdif.c | 5 +---- sound/soc/soc-topology.c | 8 ++------ sound/soc/ti/omap-hdmi.c | 5 +---- 6 files changed, 10 insertions(+), 32 deletions(-) -- 2.25.1
