[alsa-devel] Constant noise on HDA ALC275
by Julien Danjou 08 Oct '12

08 Oct '12

Hi there, I've an HDA based chipset in a new Sony Vaio Z (Ivy Bridge). As sound as the system starts and the sound module are loaded, there's a constant noise (shhhhhhht) in the speakers. The noise change a bit if I toggle the mute button, but it's still there. This noise stops as sound as I plug something in the jack port. I've tried to play with HDA Analyzer¹, but I've no clue what to look for, so any hint appreciated.

[alsa-devel] [PATCH] ALSA: hda - avoid unneccesary indices on "Headphone Jack" controls

[alsa-devel] [PATCH] ALSA: aloop - add locking to timer access
by Omair Mohammed Abdullah 08 Oct '12

08 Oct '12

When the loopback timer handler is running, calling del_timer() (for STOP trigger) will not wait for the handler to complete before deactivating the timer. The timer gets rescheduled in the handler as usual. Then a subsequent START trigger will try to start the timer using add_timer() with a timer pending leading to a kernel panic. Serialize the calls to add_timer() and del_timer() using a spin lock to avoid this.

[alsa-devel] [PATCH] ALSA: hda - Fix hang caused by race during suspend.
by Dylan Reid 08 Oct '12

08 Oct '12

There was a race condition when the system suspends while hda_power_work is running in the work queue. If system suspend (snd_hda_suspend) happens after the work queue releases power_lock but before it calls hda_call_codec_suspend, codec_suspend runs with power_on=0, causing the codec to power up for register reads, and hanging when it calls cancel_delayed_work_sync from the running work queue. The call chain from the work queue will look like this: hda_power_work <<- power_on = 1, unlock, then power_on cleard by suspend hda_call_codec_suspend hda_set_power_state snd_hda_codec_read codec_exec_verb snd_hda_power_up snd_hda_power_save __snd_hda_power_up cancel_delayed_work_sync <<-- cancelling executing wq Fix this by waiting for the work queue to finish before starting suspend if suspend is not happening on the work queue.

[alsa-devel] [PATCH] ALSA: hda/realtek - Fix detection of ALC271X codec

In commit af741c1 ("ALSA: hda/realtek - Call alc_auto_parse_customize_define() always after fixup"), alc_auto_parse_customize_define was moved after detection of ALC271X. The problem is that detection of ALC271X relies on spec->cdefine.platform_type, and it's set on alc_auto_parse_customize_define.
