Problems with Data Types, Low Severity (3)

	Change	Effect
1	Value of member SND_PCM_TYPE_LAST has been changed from 29 to 30.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

pcm.h
[+] enum _snd_pcm_type (1)

seq_event.h
[+] union anon-union-seq_event.h-432 (2)

	Change	Effect
1	Field instr_begin has been removed from this union.	Applications may access incorrect memory when attempting to access this field.
2	Field sample has been removed from this union.	Applications may access incorrect memory when attempting to access this field.

Problems with Constants (5)

	Change	Effect
1	The value of constant SNDRV_DM_FM_IOCTL_INFO has been changed from _IOR('H', 0x20, snd_dm_fm_info_t) to _IOR('H', 0x20, struct snd_dm_fm_info).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant SNDRV_DM_FM_IOCTL_PLAY_NOTE has been changed from _IOW('H', 0x22, snd_dm_fm_note_t) to _IOW('H', 0x22, struct snd_dm_fm_note).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant SNDRV_DM_FM_IOCTL_SET_PARAMS has been changed from _IOW('H', 0x24, snd_dm_fm_params_t) to _IOW('H', 0x24, struct snd_dm_fm_params).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant SNDRV_DM_FM_IOCTL_SET_VOICE has been changed from _IOW('H', 0x23, snd_dm_fm_voice_t) to _IOW('H', 0x23, struct snd_dm_fm_voice).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant IEC958_AES1_CON_ADC_ID has been changed from 0x16 to 0x06.	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
